[c-nsp] Routing table

[Jean-Christophe Varaillon]

Hi,

I have a question regarding routing tables and a possible optimization.

Internal-Routers<--->Border-Routers<--->Internet

The Border-Routers are BGP speakers:
They are receiving a full routing table from the Internet
They are receiving 10 prefixes from their Internal-Routers. 

The Border-Routers have a routing table of almost 170,000 routes.

The Border-Routers use this routing table to find the best path through
the Internet.

However they also check this huge routing table to route traffic to the
Internal-Routers.

Is there a way to have the Border-routers to check only among the 10
prefixes to route traffic from the Internet to the Internal-Routers?

Thank you,

Christophe
