route aggregation

spiker

hi everyone, im new.

I am a little confused over the term Route Aggrigation, i am assuming that an aggregate route is a summary route? but i cant find much supporting documentation for the term, anyone have any details they could pass on?

i stumbled accross the term in the practice test on this site for ccna and im at a bit of a loss...

cheers fellers

I don't have any experience with it... I read that you basically route large networks through the internet's core network. Each large network contains many smaller networks that get assigned to companies directly. Without route aggregation, you would be routing lots of different networks taking up more resources in routing tables and processing.

Look the word up on wikipedia.org

Yes route aggragation and route summarization are the same thing. Different routing protocols use the two terms, but they mean the same thing. The process of route aggragation is used to reduce the size of a routing table by taking many subnets or networks and representing them in the global routing table as 1 route.

For example:

192.16.0.0/24 - 192.16.31.0/24 can be aggragated into a single entry of 192.16.0.0/19 in the global routing table thereby reducing the size of the routing tables by 31 routes.
