Example-Configuring BGP routing between peers

Example of enabling BGP in Router A

Following is an example to enable BGP configuration in the router A.

RouterA# configure terminal
RouterA(conf)# router bgp 40000
RouterA(conf-router_bgp)# bgp router-id 10.1.1.99
RouterA(conf-router_bgp)# timers bgp 80 130
RouterA(conf-router_bgp)# neighbor 192.168.1.1 remote-as 45000
RouterA(conf-router_bgp)# exit
RouterA(conf)# 

The neighbors configured under CONFIGURATION-ROUTER-BGP mode and are defined using the neighbor remote-as command exchange only IPv4 unicast address prefixes.

Example of enabling BGP in Router B

Following is an example to enable BGP configuration in the router B.

RouterB# configure terminal
RouterB(conf)# router bgp 45000
RouterB(conf-router_bgp)# bgp router-id 172.17.1.99
RouterB(conf-router_bgp)# timers bgp 70 120
RouterB(conf-router_bgp)# neighbor 192.168.1.2 remote-as 40000
RouterB(conf-router_bgp)# exit
RouterB(conf)# 

The show ip bgp summary displays BGP configuration. Following is the sample output for show ip bgp summary command for router A.

RouterA#show ip bgp summary
BGP router identifier 10.1.1.99, local 40000
BGP local RIB : Routes to be Added 0, Replaced 0, Withdrawn 0
