CONFIGURING AGGREGATE ADDRESS  

Friday, November 14, 2008


aggregate address can be configured with the help of the aggregate-address command in the router configuration mode

you know how dumb iam .. as usually while writing down in this diary i go from backwords using the no version of the commands and show the results ... and i forgot of one prefix list and was troubleshooting like hell till now you get to know and u will laugh seeing that prefix list in action

CODE
sanjose2(config)#router bgp 100
sanjose2(config-router)#nei 172.24.1.18 route-reflector-client
sanjose2(config-router)#nei 192.168.1.5 route-reflector-client
sanjose2(config-router)#
as#2
