[c-nsp] FHRP's and STP

[Kevin Graham]

Is there a way to (safely) force any of the FHRP's into a multiple-active setup
such that the first router to see a packet can route it? Namely, I'm frustrated
by instances w/ L3 switches where the L2 topology (via STP) doesn't match the
L3 topology (via a FHRP) resulting in cases where traffic gets L2 switched by a
FHRP standby on its way to the active router only to get punted back again.

A tracking object based on STP state would probably be sufficient, though being
able to assign multiple routers to an active forwarding group seems ideal. Am I
missing something obviously?
