NAME

bgpdBorder Gateway Protocol daemon

SYNOPSIS

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

DESCRIPTION

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 4271. 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:
bgpd_flags=""
See rc(8) and rc.conf(8) for more information on the boot process and enabling daemons.
When bgpd starts up, it reads settings from a configuration file, typically bgpd.conf(5). A running bgpd process can be controlled using the bgpctl(8) utility.
The options are as follows:
 
 
-c
Force bgpd to do carp(4) demotion at startup when the demote functionality is used. Normally, bgpd will only do demotion at startup when the demotion counter for the group in question is already greater than 0. bgpd will start handling demotion after all sessions with demotion configured for the given group have been successfully established. At system startup, rc(8) has the demotion counter for the group carp increased until after bgpd is started, so this option should not be used in rc.conf(8).
 
 
-D macro=value
Define macro to be set to value on the command line. Overrides 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 /etc/bgpd.conf.
 
 
-n
Configtest mode. Only check the configuration file for validity.
 
 
-v
Produce more verbose output.
