I'm running HSRP on SVIs on two 3750 switches, the switches are connected together via a l2 etherchannel for HSRP, and a L3 connection. The switches are functioning as mostly layer three switches otherwise running OSPF.
When I go to a downstream router, that has two equal paths to the 3750s and ping the HSRP primary and virtual IP, everything works fine. But when I try to ping the secondary interface, the ping fails with .u.u.u.
The ping results look like a routing problem. I know OSPF will load balance from the upstream router to the HSRP subnet. But I still kind of confused why the router can't resolve this. In other designs I costed the links so OSPF always pointed at the primary HSRP device, and the router basically had only one route (to the primary). And this may be my issue, but I was wondering if it might be an issue with switches running HSRP on SVI's. I noticed the configuration support/syntax is rather limited on 3750s.
Any thoughts? Thanks!
