BGPCTL(8)

NAME
bgpctl - control the Border Gateway Protocol daemon

SYNOPSIS
bgpctl [-n] [-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 s for show summary.

The options are as follows:

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

-s socket
    Use socket instead of the default /var/run/bgpd.sock to communicate with bgpd(8).

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.

    irrfilter [options] as [arguments] Get the aut-num object from the Internet Routing Registry and generate bgpd filters from the policy specified therein. The aut-num object as well as the associated as-set and route objects have to be in RPSL format.

    The options are as follows:

    -o directory
        Use directory to write the filter files to.

    -4  Fetch only IPv4 prefixes from the registry.

    -6  Fetch only IPv6 prefixes from the registry.

log brief
    Disable verbose debug logging.

log verbose
    Enable verbose debug logging.

neighbor peer clear
    Stop and restart the BGP session to the specified neighbor. peer may be the neighbor's address or 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 or description.

neighbor peer down
    Take the BGP session to the specified neighbor down. peer may be the neighbor's address or 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 or description.

neighbor peer up
    Take the BGP session to the specified neighbor up. peer may be the neighbor's address or 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.

    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 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
    Reload the configuration file.

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:

    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.
    as as
        Show all entries with as anywhere in the AS path.
    empty-as
        Show all entries that are internal routes with no AS's in the AS path.
    neighbor ip
        Show only entries from the specified peer.
    peer-as as
        Show all entries with as as leftmost AS.
    source-as as
        Show all entries with as as rightmost AS.
    transit-as as
        Show all entries with as anywhere but rightmost.

    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.

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

show neighbor peer modifier
    Show detailed information about the neighbor identified by peer, which may be the neighbor's address or description, 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, and withdraws.
    timers
        Show the BGP timers.

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.
    as as

    community community
        Show all entries with community community.
    empty-as

    memory
        Show RIB memory statistics.
    neighbor peer
        Show only entries from the specified peer.
    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.

    Additionally, the following options are defined:

    selected
        Show only selected routes.
    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. This is only possible if softreconfig in is enabled for the neighbor.
    out Show the filtered routes sent to a neighbor also known as Adj-RIB-Out.

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

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