4 bgpctl — control the Border Gateway Protocol daemon
5
7 bgpctl [-jn] [-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 s 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
23 domain bgpctl is running in. To administer bgpd(8) in a differ‐
24 ent routing domain, run bgpctl in said routing domain.
25 The commands are as follows:
27 fib [table number] couple
29 Insert the learned routes into the specified Forwarding Informa‐
30 tion Base a.k.a. the kernel routing table.
31 fib [table number] decouple
33 Remove the learned routes from the specified Forwarding Informa‐
34 tion Base a.k.a. the kernel routing table.
35 log brief
37 Disable verbose debug logging.
38 log verbose
40 Enable verbose debug logging.
41 neighbor peer clear [reason]
43 Stop and restart the BGP session to the specified neighbor. If a
44 reason is provided, the reason is sent as Administrative Shutdown
45 Communication to the neighbor. peer may be the neighbor's
46 address, description or the word group followed by a group
47 description.
48 neighbor peer destroy
50 Destroy a previously cloned peer. The peer must be down before
51 calling this function. peer may be the neighbor's address,
52 description or the word group followed by a group description.
53 neighbor peer down [reason]
55 Take the BGP session to the specified neighbor down. If a reason
56 is provided, the reason is sent as Administrative Shutdown Commu‐
57 nication to the neighbor. peer may be the neighbor's address,
58 description or the word group followed by a group description.
59 neighbor peer refresh
61 Request the neighbor to re-send all routes. Note that the neigh‐
62 bor is not obliged to re-send all routes, or any routes at all,
63 even if it announced the route refresh capability. peer may be
64 the neighbor's address, description or the word group followed by
65 a group description.
66 neighbor peer up
68 Bring the BGP session to the specified neighbor up. peer may be
69 the neighbor's address, description or the word group followed by
70 a group description.
71 network add prefix [arguments]
73 Add the specified prefix to the list of announced networks. It
74 is possible to set various path attributes with additional
75 arguments. Adding a prefix will replace an existing equal pre‐
76 fix, including prefixes loaded from the configuration.
77 network bulk [arguments] [add]
79 Bulk add specified prefixes to the list of announced networks.
80 Prefixes should be sent via stdin. It is possible to set various
81 path attributes with additional arguments. If neither add or
82 delete is given, add is the default.
83 network bulk delete
85 Bulk remove the specified prefixes from the list of announced
86 networks. Prefixes should be sent via stdin.
87 network delete prefix
89 Remove the specified prefix from the list of announced networks.
90 network flush
92 Remove all dynamically (i.e. with bgpctl network add) added pre‐
93 fixes from the list of announced networks.
94 network mrt file file filter
96 Import networks from an MRT table dump for debugging purposes.
97 filter can be specified similarly to the show mrt command. Only
98 networks matching the filter will be imported.
99 network show family
101 Show all announced networks. family, if given, limits the output
102 to the given address family. The supported families are inet and
103 inet6.
104 reload [reason]

107 options in bgpd.conf(5) only take effect when the session is
108 reset: ipsec, tcp md5sig, and export [none | default-route].
