Configuring BGP
12-47
where:
ip-address is the IP address of the neighbor.
name is the name of the BGP peer group.
map-name is name of the route map. The route map allows route 0.0.0.0/0.0.0.0
to be injected conditionally.
It is important to control defaults in BGP, because a BGP neighbor, in an attempt to
advertise a default route to a specific peer, may send the default to all of its neighbors.
Example
In Figure 12-16, Router Boston originates the default route 0.0.0.0/0.0.0.0 toward
Router Miami only. Router Chicago does not receive the default route.
The following commands configure Router Boston:
MOT(config)#router bgp 100
MOT(config-bgp)#network 150.20.30.0 255.255.255.0
MOT(config-bgp)#neighbor 150.20.20.1 remote-as 200
MOT(config-bgp)#neighbor 150.20.20.1 default-originate
