Are there any caveats associated when peering in BGP with an HSRP virtual address?
I have a national ethernet circuit which terminates on a layer 2 switchport. The vlan of this switchport is then trunked to 2 Layer 3 gateway routers running HSRP between them for resiliency.
I want to set up eBGP between the CE on one end of the link and the PE routers at the other end.
Is it possible for the CE to peer with the HSRP virtual address? I'm hoping that whichever PE router is the active router for the standby group will peer with the CE and in the event of a PE router failure, the standby router will take up the responsibility of peering with the CE.
HSRP is a LAN technology, a First Hop Redundancy Protocol, and should be used on the LAN side of things IMO. Of course, we can hack things and make them work in a twisted way (some folks treat it as CCIE way :-), but would we want such a solution in a production environment? One should put together extensive redundancy testing with such implementation and there is still there is a chance for a FFFF-up simply cause the technology in use is not designed for the use-case.
