Re: OSPF Multi-hop, running bgp without ip address on physical

Rahul,

If you have the right equipment you could use L2 local switching between
the interfaces, there are however a lot of hardware restrictions. Check
this link. look at the local switching for Serial HDLC interfaces... I
couldn't get this to work with the 3640's in GNS, but I have a 7200 I'll
try later.
