Hey Sam,
It seems like you understand the issue here, but you didn't mention how I
can verify if packets between the peers are using the tunnel rather than
just the IGP.
The problem is that the usual command to verify bgp is useless (it seems) in
this scenario because peering will be established whether or not the tunnel
is being used by the BGP peers.
Thanks for your input.
Tim
