Route Summarization ... Good or Bad !

[sanjaynadarajah]

Hi,

[1] Is route summarization good or not good ? While reading, I am confused as the docs says route summaization is good as it uses less CPU cycles and less memory but on the other hand it is not that good as well as some of the routes might be lost due to route summarization.

[2] Is there a baseline when to do route summarization ?

Please enlighten me experts,

Thank you,

I think you should summarize routes whenever its possible.

If you dont have discontigous network, there's no harm doing it.

[1]. It depends on your circumstances. For smaller networks, it's not strictly necessary to summarise. For bigger networks, you will quickly run into problems if you don't summarise. The problem with summarisation is that routing may not always be optimal. But you can live with that; if your network melts down because you are carrying too many routes, then you are much worse off. So summarisation is a good thing.

[2]. See response to [1] above.

Hope that helps - pls rate the post if it does.
