    could you explain a little more about the configuration? perhaps post the different VRRP and IP configs?

     

    all in same subnet?

     

    i dont recall that certain things don't work anymore once you have the ipsec tunnel between controllers. it probably works but the traffic goes in a different direction. in principle it isn't that bad as long as your tunnels are up.

    From the local controller, I tried pinging Loopback IP of the standby controller, it was not working....

    From the local controller, I tried pinging Interface IP of the standby controller, it was working....

     

    From the standby master controller, I tried pinging Interface IP of the local controller, it was not working....

    From the standby master controller, I tried pinging Loopback IP of the local controller, it was working....

     

    Anyone knows what is the difference and why is it behaving this way? ____

    What would be the command(s) to troubleshoot the issue?

    it is likely due to the fact the IPsec tunnel is not up, meaning that there is a route-map on controller1 that has the loopback ip of controller2 down the ipsec tunnel, but since the tunnel is not up/broken/other it is just a sink. Causes include (ab)using nat-inside on vlan1, dupe ips, ipsec issues etc.

    meaning to say, if local is unable to ping to master-standby, it is due to the "sink" characteristics of the master-standby IP address, right? ____

    more to the point, it's due to the fact there is a problem with the ipsec tunnel - be it master/local or master/master-redundant
