I'm guessing by the AMD FE, this is a 2600 series. If so, check to see if
your release supports SPD, as I believe HSRP hellos will qualify for
extended headroom. May still not make the difference, in which case
bumping timers would probably be the only answer. (One can only hope that
missing the HSRP hellos would also qualify for dropping igp hellos...)
