How to perform route summarization using BGP protocol?
Do you like this story?
Route summarization is the process of replacing a series of routes into a summary route with subnet mask. The main purpose of summarization is to decrease the uses of bandwidth and make the size of routing table smaller. For example if you are trying to advertise four routes 194.1.17.0/24, 194.1.18.0/24, 194.1.19.0/24 and 194.1.20.0/24 from router C to router B then the only summarized address as 194.1.16.0 255.255.248.0 will be advertised in the update packet. Today tip will help you configure BGP route summarization between two different types of routing protocols. In this case, we will try to configure three different routers with routing protocols OSPF & RIP and then advertised one summary route from router C to router B using BGP Aggregate-address command. Follow the network topology of three different class network in given figure:
