We are running HSRP on a pair of 6509's on 24 Vlan interfaces. I have a problem that has occurred twice now and I know the quick fix, but I want to see if what the root problem is.
The switch will stop routing certain traffic. For instance, the first time it occurred, we were unable to pull up the ILO board web pages in our server VLAN. All other traffic worked fine & you could get to the said pages if you were on the same VLAN. Removing the HSRP configuration and reapplying it for that one VLAN resolved the issue. Now today we are experiencing a very similar type of issue. When using VPN into the concentrator, users can get to 192.168.1.205 server but not to the 204 or 206. Also, I can ping the 2 VLAN interfaces and the HSRP address, but not telnet to any of them.
