Hi,
I am a voice engineer. To configure MGCP gateways I have used the Cisco standard method of creating a loopback interface specially when there are redundant switch connections, e.g. GigabitEthernet0/0 and GigabitEthernet0/0. Can anybody please explain if I use "backup interface" method, would it work same way. The backup interface method also has a backup delay, not sure what is default, but secondary interface won't be active until the delay elapses. If I configure "no backup delay" would there still be an event for MGCP? Can somebody please share their experience?

I personally have my MGCP GWs configured with "backup interface" and it works just fine. I haven't tried configuring the backup interface without delay.

If your primary interface fails, is there an event for MGCP? What happens to active calls?
Update: I just found that the default delay is 0 seconds (that means "no backup delay" is not required to be explicitly added, so I assume the MGCP gateway should not experience any impact at all. If you done this testing in your environment, please confirm.
And thanks a lot for quick reply!

The calls remain up and I don't recall seeing an MGCP event.
