This brings up a question. I understand that after the initial "hi I will be handling your requests please use me as your destination mac address". (Router talking to client).
But what happens when the initial router fails and HSRP kicks in? After an unreachable, would ClientA send out an arp or would RouterB initiate the arping to re-establish connections to any client that was using RouterA after it noticed that RouterA was not responding? Scenario: ClientA ----- RouterA/B(HSRP) ------ ClientB ClientA sends a packet to ClientB ClientA talks to the Virtual RouterA/B -- RouterA/B sends to ClientB RouterA/B tells ClientA -- RouterA will be handling your requests. RouterA/B tells ClientB -- RouterA will be handling your requests to ClientA ClientA then sends more packets to ClientB via RouterA. ClientB responds to ClientA via RouterA. Janitor comes in and accidentally unplugs RouterA's power cord. ClientA now has to re-establish a connection with ClientB. I have seen the above scenario happen in a failover test when implementing a new core but did not have a bug in my ear to watch the MAC addresses. It has my curiosity perked. In theory I beleive RouterB would re-establish communication after a failed "hi are you there packet to RouterA". I will have to wait until a lab is set up to play out the scenario.
