What is the recommended memory configuration for two 2621XMs doing iBGP between each other and one with a BGP session out to VzB and one with a BGP session Sprint? I would like to know memory requirements for pulling in both Full and Partial routes. Any ideas?

No. If you are learning the same 100k prefixes from two locations then it wouldn't become 200k routes but it's 100k routes with multiple paths.

The minimum memory requirement for full routing table is 256mb but 512mb is recommended. For partial routing table it would vary based on the size of the routing table. Even if you are learning half the Internet routes you are better off having atleast 256mb.

Would the iBGP peer with the other router cause 2 full routing tables to be built?
