11.1 Starting BGP

Default configuration file of bgpd is bgpd.conf. bgpd searches the current directory first then /etc/quagga/bgpd.conf. All of bgpd’s command must be configured in bgpd.conf.

bgpd specific invocation options are described below. Common options may also be specified (see Common Invocation Options).


Set the bgp protocol’s port number.


When program terminates, retain BGP routes added by zebra.


Specify a specific IP address for bgpd to listen on, rather than its default of INADDR_ANY / IN6ADDR_ANY. This can be useful to constrain bgpd to an internal address, or to run multiple bgpd processes on one host.
