Just recently we had implemented the HSRP to our routers to support link redundancy to our production network. The diagram below explicates our network schema. We found out when HSRP was enabled on the CISCO 3640 router, we noticed that any outside HTTPS traffic is not accessible through the WebDirectors serverirons (Load balancers). The HSRP works. It routes all traffic to the 3640. We can ping each system and we can also connect via HTTPS to all systems managed (behind) by the WebDirectors. As soon as we delete the HSRP on that router, things went back to normal.
I was wondering if there is a compatibility issue with HSRP between the CISCO 3640 router and the WebDirectors? Is there any special configuration parameters that we need to implement to the WebDirectors so that HSRP to work on our CISCO routers? Is there a possibilty that the Webdirectors might be seeing the wrong ARP cache for the HSRP VIP?
If you think it is a MAC issue, you can use the STANDBY USE-BIA on both HSRP routers to use the real MAC of the interface instead of the virtual MAC which floats between the HSRP routers. Also, be careful of the priority of standby router. If you use a track command, the priority drops by 10 so the standby will never become active as both priority of the Active and Standby will be equal. Also, remember your default gateway is now the HSRP IP address so make sure there are no changes to be made on your serverirons
