Figure 12-14 Configuring the Local Preference Attribute
Router New York sets the local preference for all updates from AS 200 to 125. Router
Boston sets the local preference for all updates from AS 400 to 200. Because Router
New York and Router Boston exchange local preference information within AS 100,
they recognize that updates regarding network 156.10.0.0 have higher local
preference when they come to AS 100 from AS 400 than from AS 200.
The following commands configure Router New York:
MOT(config)#router bgp 100
MOT(config-bgp)#neighbor 140.20.30.2 remote-as 100
MOT(config-bgp)#neighbor 192.30.10.1 remote-as 200
MOT(config-bgp)#bgp default local-preference 125
The following commands configure Router Boston:
MOT(config)#router bgp 100
MOT(config-bgp)#neighbor 140.20.30.1 remote-as 100
MOT(config-bgp)#neighbor 192.56.10.2 remote-as 400
MOT(config-bgp)#bgp default local-preference 200
