Ubuntu Manpage: bgpctl — control the Border Gateway Protocol daemon

NAME

       bgpctl — control the Border Gateway Protocol daemon

SYNOPSIS

       bgpctl [-jnV] [-s socket] command [argument ...]

DESCRIPTION

The bgpctl program controls the bgpd(8) daemon. Commands may be abbreviated to the minimum unambiguous
prefix; for example, s su for show summary.

The options are as follows:

-j Create output as JSON object.

-n Show neighbors' IP addresses instead of their description.

-s socket
Use socket to communicate with bgpd(8) instead of the default /run/bgpd.sock.<rdomain> where
<rdomain> is the routing domain bgpctl is running in. To administer bgpd(8) in a different
routing domain, run bgpctl in said routing domain.

-V Show the version and exit.

The commands are as follows:

fib [table number] couple
Insert the learned routes into the specified Forwarding Information Base a.k.a. the kernel
routing table.

fib [table number] decouple
Remove the learned routes from the specified Forwarding Information Base a.k.a. the kernel
routing table.

log brief
Disable verbose debug logging.

log verbose
Enable verbose debug logging.

neighbor peer clear [reason]
Stop and restart the BGP session to the specified neighbor. If a reason is provided, the reason
is sent as Administrative Shutdown Communication to the neighbor. peer may be the neighbor's
address, description or the word group followed by a group description.

neighbor peer destroy
Destroy a previously cloned peer. The peer must be down before calling this function. peer may
be the neighbor's address, description or the word group followed by a group description.

neighbor peer down [reason]
Take the BGP session to the specified neighbor down. If a reason is provided, the reason is sent
as Administrative Shutdown Communication to the neighbor. peer may be the neighbor's address,
description or the word group followed by a group description.

neighbor peer refresh
Request the neighbor to re-send all routes. Note that the neighbor is not obliged to re-send all
routes, or any routes at all, even if it announced the route refresh capability. peer may be the
neighbor's address, description or the word group followed by a group description.

neighbor peer up
Bring the BGP session to the specified neighbor up. peer may be the neighbor's address,
description or the word group followed by a group description.

network add prefix [arguments]
Add the specified prefix to the list of announced networks. It is possible to set various path
attributes with additional arguments. Adding a prefix will replace an existing equal prefix,
including prefixes loaded from the configuration.

network bulk [arguments] [add]
Bulk add specified prefixes to the list of announced networks. Prefixes should be sent via
stdin. It is possible to set various path attributes with additional arguments. If neither add
or delete is given, add is the default.

network bulk delete
Bulk remove the specified prefixes from the list of announced networks. Prefixes should be sent
via stdin.

network delete prefix
Remove the specified prefix from the list of announced networks.

network flush
Remove all dynamically (i.e. with bgpctl network add) added prefixes from the list of announced
networks.

network mrt file file filter
Import networks from an MRT table dump for debugging purposes. filter can be specified similarly
to the show mrt command. Only networks matching the filter will be imported.

network show family
Show all announced networks. family, if given, limits the output to the given address family.
The supported families are inet and inet6.

reload [reason]
Reload the configuration file. Changes to the following neighbor options in bgpd.conf(5) only
take effect when the session is reset: ipsec and tcp md5sig.

show fib filter
Show routes from bgpd(8)'s view of the Forwarding Information Base. filter can be an IP address,
in which case the route to this address is shown, or a flag:

connected Show only connected routes.
static Show only static routes.
bgp Show only routes originating from bgpd(8) itself.
nexthop Show only routes required to reach a BGP nexthop.
inet Show only IPv4 routes.
inet6 Show only IPv6 routes.
table number Show the routing table with ID number instead of the default routing table with ID
0.

show interfaces
Show the interface states.

show mrt [options] filter
Show routes from an MRT table dump file. filter can be an IP address, a CIDR prefix, an AS
filter, a combination or nothing:

Additionally, the following options are defined:

detail Show more detailed output for matching routes.
family Limit the output to the given address family.
file name Read the MRT dump from file name instead of using stdin.
peers Print the neighbor table of MRT TABLE_DUMP_V2 dumps. Using this on other table dumps
will only show the neighbor of the first entry.

Multiple options and filters can be used at the same time.

show neighbor peer modifier
Show detailed information about the neighbor identified by peer, according to the given modifier:

messages Show statistics about sent and received BGP messages.
terse Show statistics in an easily parseable terse format. The printed numbers are the sent
and received open, sent and received notifications, sent and received updates, sent and
received keepalives, and sent and received route refresh messages plus the current and
maximum prefix count, the number of sent and received updates, sent and received
withdraws, the neighbor's address (or subnet, for a template), AS number, and finally
description.
timers Show the BGP timers.
peer may be the neighbor's address, description or the word group followed by a group
description.

show nexthop
Show the list of BGP nexthops and the result of their validity check.

show rib [options] filter
Show routes from the bgpd(8) Routing Information Base. filter can be an IP address, a CIDR
prefix, an AS filter or nothing:

address Show best matching route for address.
address/len Show RIB entry for this CIDR prefix.
address/len all Show all entries in the specified range.
address/len or-shorter Show all entries covering and including the specified prefix.
as as Show all entries with as anywhere in the AS path.
community community Show all entries with community community.
large-community large-community
Show all entries with large-community large-community.
empty-as Show all entries that are internal routes with no AS's in the AS path.
memory Show RIB memory statistics.
neighbor peer Show only entries from the specified peer.
neighbor group description
Show only entries from the specified peer group.
path-id pathid Show only entries which match the specified pathid. Must be used
together with either neighbor or out.
peer-as as Show all entries with as as leftmost AS.
source-as as Show all entries with as as rightmost AS.
summary This is the same as the show summary command.
table rib Show only entries from the specified RIB table.
transit-as as Show all entries with as anywhere but rightmost.
ovs (valid | not-found | invalid)
Show all entries with matching Origin Validation State (OVS).

Additionally, the following options are defined:

best Alias for selected.
error Show only prefixes which are marked invalid and were treated as withdrawn.
selected Show only selected routes.
ssv Show each RIB entry as a single line, with fields separated by semicolons. Only works
if detail is specified.
detail Show more detailed output for matching routes.
family Limit the output to the given address family.
in Show routes from the unfiltered Adj-RIB-In. The neighbor needs to be specified.
out Show the filtered routes sent to a neighbor. The neighbor needs to be specified.

Options are silently ignored when used together with summary or memory. Multiple options can be
used at the same time and the neighbor filter can be combined with other filters.

show rtr
Show a list of all RTR sessions, including information about the session state.

show sets
Show a list summarizing all roa-set, as-set, prefix-set, and origin-set tables.

show summary
Show a list of all neighbors, including information about the session state and message counters:

Neighbor Description of the neighbor.
AS Autonomous system number.
MsgRcvd Number of messages received from the neighbor.
MsgSent Number of messages sent to the neighbor.
OutQ Number of outgoing messages queued.
Up/Down Number of days and hours that the session has been up.
State/PrfRcvd State of the session / Number of routes received. The session is up if there is
no information for the State column (Established is not displayed).

show summary terse
Show a list of all neighbors, including information about the session state, in a terse format.

show tables
Show a list of all currently loaded fib routing tables.
