How to perform route summarization in OSPF protocols?
Do you like this story?
Route summarization is a process to merge a list of several routes into a single route. The main benefit of route summarization is to shrinking router tables and also reducing the size of update traffic. But the ultimate goal is to decrease the uses of bandwidth and processing time. For example if you are trying to advertise four different routes 196.1.17.0/24, 196.1.18.0/24, 196.1.19.0/24 and 196.1.20.0/24 from router A to router B then the only summarized address as 196.1.16.0 255.255.248.0 will be advertised in the update packet. In OSPF, you can perform two types of route summarization, inter-area route summarization and external route summarization. Today tip will help you configure OSPF route summarization between two different types of autonomous systems. In this case, we will try to configure two different routers with routing protocols OSPF & create four static routes and then advertised one summary route from router A to router B using summary-address command.
