|BGPD(8)||System Manager's Manual||BGPD(8)|
bgpdis 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.
bgpduses 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
The options are as follows:
bgpdto do carp(4) demotion at startup when the demote functionality is used. Normally,
bgpdwill only do demotion at startup when the demotion counter for the group in question is already greater than 0.
bgpdwill 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
bgpdis started, so this option should not be used in rc.conf(8).
bgpdwill run in the foreground and log to stderr.
