BGPD(8)                 OpenBSD System Manager's Manual                BGPD(8)

     bgpd - Border Gateway Protocol daemon

     bgpd [-dnv] [-D macro=value] [-f file]

     bgpd is a Border Gateway Protocol (BGP) daemon which manages the network
     routing tables.  Its main purpose is to exchange information concerning
     "network reachability" with other BGP systems.  bgpd uses the Border
     Gateway Protocol, Version 4, as described in RFC 1771.  Please refer to
     that document for more information about BGP.

     bgpd is usually started at boot time, and can be enabled by setting the
     following in /etc/rc.conf.local:


     See rc(8) and rc.conf(8) for more information on the boot process and en-
     abling daemons.

     When bgpd starts up, it reads settings from a configuration file, typi-
     cally bgpd.conf(5).  A running bgpd process can be controlled using the
     bgpctl(8) utility.

     The options are as follows:

     -D macro=value
                 Define macro to be set to value on the command line.  Over-
                 rides the definition of macro in the configuration file.

     -d          Do not daemonize.  If this option is specified, bgpd will run
                 in the foreground and log to stderr.

     -f file     Use file as the configuration file, instead of the default

     -n          Configtest mode.  Only check the configuration file for va-

     -v          Produce more verbose output.
