Hi Guys,
even if it works, why would you want to do it? When a failure occurs,
first the HSRP has to swap over, then the BGP has to reconverge. If you
run the BGP (or any other protocol for that matter) between ordinary
interfaces, it can stay up to one of the boxes when the other goes down.
So there would be less time lost in recovering from a failure. HSRP and
the like are intended really for first hop redundancy, where the other
end of the hop is something that is not smart enough to run a routing
protocol so only has a default gateway. configured.
At least...it seems like that to me....I haven't tried to lab it up.
Also your two routers in the HSRP pair will possibly have different
views of the network around them, so if they are advertising routes into
BGP, those routes may change each time the HSRP swaps over, and that
will have to propagate through the rest of the BGP network. That seems
like adding unnecessary load to all the other routers in the BGP peering.
regards
John

Here's someone from Cisco agreeing that it works but pointing out one of
the issues mentioned earlier, that the routers doing HSRP wouldn't be able
to initiate the BGP open:
