Okay....... we've got a 5513 with RSM and a 6509 with Sup2 + MSFC2... they are trunked together (at layer 2). I've got HSRP configured for 7 other VLANs on the same two switches and don't have this problem with any of them except this one VLAN.
I would try to explain the problem, but here's output and config snippets from the two routers to demonstrate the problem (i.e. look at the output from the 'show stand vlan 300' command on HQ5). I've also included pings between to two to demonstrate that they can indeed communicate with each other......... Remember that none of the other VLANs (with virtually the exact same config except for different IPs/subnets works fine) Any input is appreciated!
