4 bgpctl — control the Border Gateway Protocol daemon
5
7 bgpctl [-jnV] [-s socket] command [argument ...]
8
10 The bgpctl program controls the bgpd(8) daemon. Commands may be abbrevi‐
11 ated to the minimum unambiguous prefix; for example, s su for show
12 summary.
13 The options are as follows:
15 -j Create output as JSON object.
17 -n Show neighbors' IP addresses instead of their description.
19 -s socket
21 Use socket to communicate with bgpd(8) instead of the default
22 /run/bgpd/bgpd.sock.<rdomain> where <rdomain> is the routing do‐
23 main bgpctl is running in. To administer bgpd(8) in a different
24 routing domain, run bgpctl in said routing domain.
25 -V Show the version and exit.
27 The commands are as follows:
29 fib [table number] couple
31 Insert the learned routes into the specified Forwarding Informa‐
32 tion Base a.k.a. the kernel routing table.
33 fib [table number] decouple
35 Remove the learned routes from the specified Forwarding Informa‐
36 tion Base a.k.a. the kernel routing table.
37 log brief
39 Disable verbose debug logging.
40 log verbose
42 Enable verbose debug logging.
43 neighbor peer clear [reason]
45 Stop and restart the BGP session to the specified neighbor. If a
46 reason is provided, the reason is sent as Administrative Shutdown
47 Communication to the neighbor. peer may be the neighbor's ad‐
48 dress, description or the word group followed by a group descrip‐
49 tion.
50 neighbor peer destroy
52 Destroy a previously cloned peer. The peer must be down before
53 calling this function. peer may be the neighbor's address, de‐
54 scription or the word group followed by a group description.
55 neighbor peer down [reason]
57 Take the BGP session to the specified neighbor down. If a reason
58 is provided, the reason is sent as Administrative Shutdown Commu‐
59 nication to the neighbor. peer may be the neighbor's address,
60 description or the word group followed by a group description.
61 neighbor peer refresh
63 Request the neighbor to re-send all routes. Note that the neigh‐
64 bor is not obliged to re-send all routes, or any routes at all,
65 even if it announced the route refresh capability. peer may be
66 the neighbor's address, description or the word group followed by
67 a group description.
68 neighbor peer up
70 Bring the BGP session to the specified neighbor up. peer may be
71 the neighbor's address, description or the word group followed by
72 a group description.
73 network add prefix [arguments]
75 Add the specified prefix to the list of announced networks. It
76 is possible to set various path attributes with additional
77 arguments. Adding a prefix will replace an existing equal pre‐
78 fix, including prefixes loaded from the configuration.
79 network bulk [arguments] [add]
81 Bulk add specified prefixes to the list of announced networks.
82 Prefixes should be sent via stdin. It is possible to set various
83 path attributes with additional arguments. If neither add or
84 delete is given, add is the default.
85 network bulk delete
87 Bulk remove the specified prefixes from the list of announced
88 networks. Prefixes should be sent via stdin.
89 network delete prefix
91 Remove the specified prefix from the list of announced networks.
92 network flush
94 Remove all dynamically (i.e. with bgpctl network add) added pre‐
95 fixes from the list of announced networks.
96 network mrt file file filter
98 Import networks from an MRT table dump for debugging purposes.
99 filter can be specified similarly to the show mrt command. Only
100 networks matching the filter will be imported.
101 network show family
103 Show all announced networks. family, if given, limits the output
104 to the given address family. The supported families are inet and
105 inet6.
106 reload [reason]

109 options in bgpd.conf(5) only take effect when the session is re‐
110 set: ipsec and tcp md5sig.
