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

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.  I have few
other routers (ASR1K, 7600) that would normally be used for that, but
are in far-away locations. Of course I can set up a local BGP session
and then add a multihop one for the full feed, but that doesn't seem
like an elegant solution any more. All the routers run MPLS, so if I
could get a xconnect going between one of the bigger boxes and the
small PE, without actually wasting port on the bigger router (by
having some sort of logical interface) then I could run the BGP
session directly. I had a look on Cisco website, but either it's not
possible or that kind of bridging has a special name that I can't pin
down. If you've heard of such feature - please let me know.

kind regards
Pshem
