11.4.1 BGP route

BGP: network A.B.C.D/M

This command adds the announcement network.

router bgp 1
 network 10.0.0.0/8

This configuration example says that network 10.0.0.0/8 will be announced to all neighbors. Some vendors’ routers don’t advertise routes if they aren’t present in their IGP routing tables; bgpd doesn’t care about IGP routes when announcing its routes.

BGP: no network A.B.C.D/M
