Line 465:
= Auto-Summarization =
* Normally when you advertise a network in BGP you have to type in the exact network and subnet mask that you want to advertise or it won’t be placed in the BGP table.
* With auto-summary enabled, you can advertise a classful network and you don’t have to add the mask parameter.
* BGP will automatically advertise the classful network if you have the classful network or a subnet of this network in your routing table.
Config:
R1(config)#router bgp 1
