Figure 25. Route Aggregation and Default Route Redistribution
1. Configure the IP interface.
2. Configure the AS number (AS 135) and router ID (10.1.1.135)
>> # router bgp
>> (config-router-bgp)# as 135
>> (config-router-bgp)# exit
>> # ip router-id 10.1.1.135
3. Configure internal peer router 1 and external peer router 2 with IPv4
addresses.
>> # router bgp
>> (config-router-bgp)# neighbor 1 remote-address 10.1.1.4
>> (config-router-bgp)# neighbor 1 remote-as 135
>> (config-router-bgp)# neighbor 2 remote-address 20.20.20.2
>> (config-router-bgp)# neighbor 2 remote-as 200
4. Configure redistribution for Peer 1.
>> (config-router-bgp)# neighbor 1 redistribute default-action
redistribute
>> (config-router-bgp)# neighbor 1 redistribute fixed
5. Configure aggregation policy control.
Configure the IPv4 routes that you want aggregated.
>> (config-router-bgp)# aggregate-address 1 135.0.0.0 255.0.0.0
>> (config-router-bgp)# aggregate-address 1 enable
