DESCRIPTION

82       ip route is used to manipulate entries in the kernel routing tables.
83
84       Route types:
85
86               unicast - the route entry describes real paths to the destina‐
87               tions covered by the route prefix.
88
89
90               unreachable - these destinations are unreachable. Packets are
91               discarded and the ICMP message host unreachable is generated.
92               The local senders get an EHOSTUNREACH error.
93
94
95               blackhole - these destinations are unreachable. Packets are
96               discarded silently.  The local senders get an EINVAL error.
97
98
99               prohibit - these destinations are unreachable. Packets are dis‐
100               carded and the ICMP message communication administratively pro‐
101               hibited is generated. The local senders get an EACCES error.
102
103
104               local - the destinations are assigned to this host. The packets
105               are looped back and delivered locally.
106
107
108               broadcast - the destinations are broadcast addresses. The pack‐
109               ets are sent as link broadcasts.
110
111
112               throw - a special control route used together with policy
113               rules. If such a route is selected, lookup in this table is
114               terminated pretending that no route was found. Without policy
115               routing it is equivalent to the absence of the route in the
116               routing table. The packets are dropped and the ICMP message net
117               unreachable is generated. The local senders get an ENETUNREACH
118               error.
119
120
121               nat - a special NAT route. Destinations covered by the prefix
122               are considered to be dummy (or external) addresses which
123               require translation to real (or internal) ones before forward‐
124               ing. The addresses to translate to are selected with the
125               attribute via.  Warning: Route NAT is no longer supported in
126               Linux 2.6.
127
128
129               anycast - not implemented the destinations are anycast
130               addresses assigned to this host. They are mainly equivalent to
131               local with one difference: such addresses are invalid when used
132               as the source address of any packet.
133
134
135               multicast - a special type used for multicast routing. It is
136               not present in normal routing tables.
137
138
139       Route tables: Linux-2.x can pack routes into several routing tables
140       identified by a number in the range from 1 to 2^32-1 or by name from
141       the file /etc/iproute2/rt_tables By default all normal routes are
142       inserted into the main table (ID 254) and the kernel only uses this ta‐
143       ble when calculating routes.  Values (0, 253, 254, and 255) are
144       reserved for built-in use.
145
146
147       Actually, one other table always exists, which is invisible but even
148       more important. It is the local table (ID 255). This table consists of
149       routes for local and broadcast addresses. The kernel maintains this ta‐
150       ble automatically and the administrator usually need not modify it or
151       even look at it.
152
153       The multiple routing tables enter the game when policy routing is used.
154
155
156       ip route add
157              add new route
158
159       ip route change
160              change route
161
162       ip route replace
163              change or add new one
164
165              to TYPE PREFIX (default)
166                     the destination prefix of the route. If TYPE is omitted,
167                     ip assumes type unicast.  Other values of TYPE are listed
168                     above.  PREFIX is an IP or IPv6 address optionally fol‐
169                     lowed by a slash and the prefix length. If the length of
170                     the prefix is missing, ip assumes a full-length host
171                     route. There is also a special PREFIX default - which is
172                     equivalent to IP 0/0 or to IPv6 ::/0.
173
174
175              tos TOS
176
177              dsfield TOS
178                     the Type Of Service (TOS) key. This key has no associated
179                     mask and the longest match is understood as: First, com‐
180                     pare the TOS of the route and of the packet. If they are
181                     not equal, then the packet may still match a route with a
182                     zero TOS.  TOS is either an 8 bit hexadecimal number or
183                     an identifier from /etc/iproute2/rt_dsfield.
184
185
186              metric NUMBER
187
188              preference NUMBER
189                     the preference value of the route.  NUMBER is an arbi‐
190                     trary 32bit number, where routes with lower values are
191                     preferred.
192
193
194              table TABLEID
195                     the table to add this route to.  TABLEID may be a number
196                     or a string from the file /etc/iproute2/rt_tables.  If
197                     this parameter is omitted, ip assumes the main table,
198                     with the exception of local, broadcast and nat routes,
199                     which are put into the local table by default.
200
201
202              vrf NAME
203                     the vrf name to add this route to. Implicitly means the
204                     table associated with the VRF.
205
206
207              dev NAME
208                     the output device name.
209
210
211              via [ FAMILY ] ADDRESS
212                     the address of the nexthop router, in the address family
213                     FAMILY.  Actually, the sense of this field depends on the
214                     route type.  For normal unicast routes it is either the
215                     true next hop router or, if it is a direct route
216                     installed in BSD compatibility mode, it can be a local
217                     address of the interface. For NAT routes it is the first
218                     address of the block of translated IP destinations.
219
220
221              src ADDRESS
222                     the source address to prefer when sending to the destina‐
223                     tions covered by the route prefix.
224
225
226              realm REALMID
227                     the realm to which this route is assigned.  REALMID may
228                     be a number or a string from the file
229                     /etc/iproute2/rt_realms.
230
231
232              mtu MTU
233
234              mtu lock MTU
235                     the MTU along the path to the destination. If the modi‐
236                     fier lock is not used, the MTU may be updated by the ker‐
237                     nel due to Path MTU Discovery. If the modifier lock is
238                     used, no path MTU discovery will be tried, all packets
239                     will be sent without the DF bit in IPv4 case or frag‐
240                     mented to MTU for IPv6.
241
242
243              window NUMBER
244                     the maximal window for TCP to advertise to these destina‐
245                     tions, measured in bytes. It limits maximal data bursts
246                     that our TCP peers are allowed to send to us.
247
248
249              rtt TIME
250                     the initial RTT ('Round Trip Time') estimate. If no suf‐
251                     fix is specified the units are raw values passed directly
252                     to the routing code to maintain compatibility with previ‐
253                     ous releases.  Otherwise if a suffix of s, sec or secs is
254                     used to specify seconds and ms, msec or msecs to specify
255                     milliseconds.
256
257
258
259              rttvar TIME (Linux 2.3.15+ only)
260                     the initial RTT variance estimate. Values are specified
261                     as with rtt above.
262
263
264              rto_min TIME (Linux 2.6.23+ only)
265                     the minimum TCP Retransmission TimeOut to use when commu‐
266                     nicating with this destination. Values are specified as
267                     with rtt above.
268
269
270              ssthresh NUMBER (Linux 2.3.15+ only)
271                     an estimate for the initial slow start threshold.
272
273
274              cwnd NUMBER (Linux 2.3.15+ only)
275                     the clamp for congestion window. It is ignored if the
276                     lock flag is not used.
277
278
279              initcwnd NUMBER (Linux 2.5.70+ only)
280                     the initial congestion window size for connections to
281                     this destination.  Actual window size is this value mul‐
282                     tiplied by the MSS (``Maximal Segment Size'') for same
283                     connection. The default is zero, meaning to use the val‐
284                     ues specified in RFC2414.
285
286
287              initrwnd NUMBER (Linux 2.6.33+ only)
288                     the initial receive window size for connections to this
289                     destination.  Actual window size is this value multiplied
290                     by the MSS of the connection.  The default value is zero,
291                     meaning to use Slow Start value.
292
293
294              features FEATURES (Linux3.18+only)
295                     Enable or disable per-route features. Only available fea‐
296                     ture at this time is ecn to enable explicit congestion
297                     notification when initiating connections to the given
298                     destination network.  When responding to a connection
299                     request from the given network, ecn will also be used
300                     even if the net.ipv4.tcp_ecn sysctl is set to 0.
301
302
303              quickack BOOL (Linux 3.11+ only)
304                     Enable or disable quick ack for connections to this des‐
305                     tination.
306
307
308              fastopen_no_cookie BOOL (Linux 4.15+ only)
309                     Enable TCP Fastopen without a cookie for connections to
310                     this destination.
311
312
313              congctl NAME (Linux 3.20+ only)
314
315              congctl lock NAME (Linux 3.20+ only)
316                     Sets a specific TCP congestion control algorithm only for
317                     a given destination.  If not specified, Linux keeps the
318                     current global default TCP congestion control algorithm,
319                     or the one set from the application. If the modifier lock
320                     is not used, an application may nevertheless overwrite
321                     the suggested congestion control algorithm for that des‐
322                     tination. If the modifier lock is used, then an applica‐
323                     tion is not allowed to overwrite the specified congestion
324                     control algorithm for that destination, thus it will be
325                     enforced/guaranteed to use the proposed algorithm.
326
327
328              advmss NUMBER (Linux 2.3.15+ only)
329                     the MSS ('Maximal Segment Size') to advertise to these
330                     destinations when establishing TCP connections. If it is
331                     not given, Linux uses a default value calculated from the
332                     first hop device MTU.  (If the path to these destination
333                     is asymmetric, this guess may be wrong.)
334
335
336              reordering NUMBER (Linux 2.3.15+ only)
337                     Maximal reordering on the path to this destination.  If
338                     it is not given, Linux uses the value selected with
339                     sysctl variable net/ipv4/tcp_reordering.
340
341
342              nexthop NEXTHOP
343                     the nexthop of a multipath route.  NEXTHOP is a complex
344                     value with its own syntax similar to the top level argu‐
345                     ment lists:
346
347                             via [ FAMILY ] ADDRESS - is the nexthop router.
348
349
350                             dev NAME - is the output device.
351
352
353                             weight NUMBER - is a weight for this element of a
354                             multipath route reflecting its relative bandwidth
355                             or quality.

357                     The internal buffer used in iproute2 limits the maximum
358                     number of nexthops that may be specified in one go. If
359                     only ADDRESS is given, the current buffer size allows for
360                     144 IPv6 nexthops and 253 IPv4 ones. For IPv4, this
361                     effectively limits the number of nexthops possible per
362                     route. With IPv6, further nexthops may be appended to the
363                     same route via ip route append command.
364
365
366              scope SCOPE_VAL
367                     the scope of the destinations covered by the route pre‐
368                     fix.  SCOPE_VAL may be a number or a string from the file
369                     /etc/iproute2/rt_scopes.  If this parameter is omitted,
370                     ip assumes scope global for all gatewayed unicast routes,
371                     scope link for direct unicast and broadcast routes and
372                     scope host for local routes.
373
374
375              protocol RTPROTO
376                     the routing protocol identifier of this route.  RTPROTO
377                     may be a number or a string from the file
378                     /etc/iproute2/rt_protos.  If the routing protocol ID is
379                     not given, ip assumes protocol boot (i.e. it assumes the
380                     route was added by someone who doesn't understand what
381                     they are doing). Several protocol values have a fixed
382                     interpretation.  Namely:
383
384                             redirect - the route was installed due to an ICMP
385                             redirect.
386
387
388                             kernel - the route was installed by the kernel
389                             during autoconfiguration.
390
391
392                             boot - the route was installed during the bootup
393                             sequence.  If a routing daemon starts, it will
394                             purge all of them.
395
396
397                             static - the route was installed by the adminis‐
398                             trator to override dynamic routing. Routing dae‐
399                             mon will respect them and, probably, even adver‐
400                             tise them to its peers.
401
402
403                             ra - the route was installed by Router Discovery
404                             protocol.
405
406
407                     The rest of the values are not reserved and the adminis‐
408                     trator is free to assign (or not to assign) protocol
409                     tags.

412              onlink pretend that the nexthop is directly attached to this
413                     link, even if it does not match any interface prefix.
414
415
416              pref PREF
417                     the IPv6 route preference.  PREF is a string specifying
418                     the route preference as defined in RFC4191 for Router
419                     Discovery messages. Namely:
420
421                             low - the route has a lowest priority
422
423
424                             medium - the route has a default priority
425
426
427                             high - the route has a highest priority
428

431              encap ENCAPTYPE ENCAPHDR
432                     attach tunnel encapsulation attributes to this route.
433
434                     ENCAPTYPE is a string specifying the supported encapsula‐
435                     tion type. Namely:
436
437                             mpls - encapsulation type MPLS
438
439                             ip - IP encapsulation (Geneve, GRE, VXLAN, ...)

561       ip route delete

563              ip route del has the same arguments as ip route add, but their
564              semantics are a bit different.
565
566              Key values (to, tos, preference and table) select the route to
567              delete. If optional attributes are present, ip verifies that
568              they coincide with the attributes of the route to delete.  If no
569              route with the given key and attributes was found, ip route del
570              fails.
571
572
573       ip route show
574              list routes
575              the command displays the contents of the routing tables or the

579              to SELECTOR (default)
580                     only select routes from the given range of destinations.
581                     SELECTOR consists of an optional modifier (root, match or
582                     exact) and a prefix.  root PREFIX selects routes with
583                     prefixes not shorter than PREFIX.  F.e.  root 0/0 selects
584                     the entire routing table.  match PREFIX selects routes
585                     with prefixes not longer than PREFIX.  F.e.  match
586                     10.0/16 selects 10.0/16, 10/8 and 0/0, but it does not
587                     select 10.1/16 and 10.0.0/24.  And exact PREFIX (or just
588                     PREFIX) selects routes with this exact prefix. If neither
589                     of these options are present, ip assumes root 0/0 i.e. it
590                     lists the entire table.
591

599              table TABLEID
600                     show the routes from this table(s). The default setting
601                     is to show table main.  TABLEID may either be the ID of a
602                     real table or one of the special values:
603
604                             all - list all of the tables.
605
606                             cache - dump the routing cache.

617                     forked from other routes because some route attribute
618                     (f.e. MTU) was updated.  Actually, it is equivalent to
619                     table cache.

623                     the same syntax as for to, but it binds the source
624                     address range rather than destinations.  Note that the
625                     from option only works with cloned routes.

662              this command flushes routes selected by some criteria.
663
664
665              The arguments have the same syntax and semantics as the argu‐
666              ments of ip route show, but routing tables are not listed but
667              purged. The only difference is the default action: show dumps
668              all the IP main routing table but flush prints the helper page.
669
670
671              With the -statistics option, the command becomes verbose. It
672              prints out the number of deleted routes and the number of rounds
673              made to flush the routing table. If the option is given twice,
674              ip route flush also dumps all the deleted routes in the format
675              described in the previous subsection.
676
677
678       ip route get
679              get a single route
680              this command gets a single route to a destination and prints its
681              contents exactly as the kernel sees it.
682
683
684              fibmatch
685                     Return full fib lookup matched route. Default is to
686                     return the resolved dst entry
687
688
689              to ADDRESS (default)
690                     the destination address.
691
692
693              from ADDRESS
694                     the source address.
695
696
697              tos TOS
698
699              dsfield TOS
700                     the Type Of Service.
701
702
703              iif NAME
704                     the device from which this packet is expected to arrive.
705
706
707              oif NAME
708                     force the output device on which this packet will be
709                     routed.
710
711
712              mark MARK
713                     the firewall mark (fwmark)
714
715
716              vrf NAME
717                     force the vrf device on which this packet will be routed.
718
719
720              ipproto PROTOCOL
721                     ip protocol as seen by the route lookup
722
723
724              sport NUMBER
725                     source port as seen by the route lookup
726
727
728              dport NUMBER
729                     destination port as seen by the route lookup
730
731
732              connected
733                     if no source address (option from) was given, relookup
734                     the route with the source set to the preferred address
735                     received from the first lookup.  If policy routing is
736                     used, it may be a different route.
737
738
739              Note that this operation is not equivalent to ip route show.
740              show shows existing routes.  get resolves them and creates new
741              clones if necessary. Essentially, get is equivalent to sending a
742              packet along this path.  If the iif argument is not given, the
743              kernel creates a route to output packets towards the requested
744              destination.  This is equivalent to pinging the destination with
745              a subsequent ip route ls cache, however, no packets are actually
746              sent. With the iif argument, the kernel pretends that a packet
747              arrived from this interface and searches for a path to forward
748              the packet.
749
750
751       ip route save
752              save routing table information to stdout
753              This command behaves like ip route show except that the output
754              is raw data suitable for passing to ip route restore.
755
756
757       ip route restore
758              restore routing table information from stdin
759              This command expects to read a data stream as returned from ip
760              route save.  It will attempt to restore the routing table infor‐
761              mation exactly as it was at the time of the save, so any trans‐
762              lation of information in the stream (such as device indexes)
763              must be done first. Any existing routes are left unchanged. Any
764              routes specified in the data stream that already exist in the
765              table will be ignored.
766
767

NOTES

769       Starting with Linux kernel version 3.6, there is no routing cache for
770       IPv4 anymore. Hence ip route show cached will never print any entries
771       on systems with this or newer kernel versions.

782       ip route add 10.1.1.0/30 encap mpls 200/300 via 10.1.1.1 dev eth0
783           Adds an ipv4 route with mpls encapsulation attributes attached to
784           it.
785
786       ip -6 route add 2001:db8:1::/64 encap seg6 mode encap segs
787       2001:db8:42::1,2001:db8:ffff::2 dev eth0
788           Adds an IPv6 route with SRv6 encapsulation and two segments
789           attached.
