Can I configure HSRP to run between two ports on the same router? I want to implement port level Layer 3 redundancy. Typically this is done using two different routers (better) but we have a single router. I have 2 HWIC-1FE ports that will be connected to the same network. I want the devices at the other end to have a single virtual IP to point to so that when a port fails on the 3825 a new active port is elected and traffic continues to flow. I've been told that HSRP will only run on 2 or more routers.
