Re: RIP and BGP

Hi Bhaskar!

The RIP database holds only the RIP routes that are
currently used by the router (that means installed in
the routing table).
Once the RIP networks are replaced in the routing
table with the eBGP entries (that have lower AD), they
will be also taken out of the RIP database. This is
RIP's normal behavior.

Hope this helps,

Mihai
