The multihop BGP solution might be the best one with least overhead; however you should be able to use a GRE tunnel if you still want to do this:
interface Tunnel1 ip address 10.10.10.1 255.255.255.252 tunnel source FastEthernet0/0 tunnel destination small.router.ip interface Tunnel1 ip address 10.10.10.2 255.255.255.252 tunnel source FastEthernet0/0 tunnel destination big.router.ip -k On Thu, Jul 15, 2010 at 7:40 PM, Pshem Kowalczyk <pshe...@gmail.com> wrote: > Hi, > > I have a situation, where a customer wants a full BGP table > (persuasion failed already), but is connected to small router (2821), > with not enough memory to get anywhere near full table.
