Do gatekeepers need a dedicated physical interface

I recently took control of a network that has several h323 vtc endpoints registered to a gatekeeper.

The 3700 router that is the gatekeeper has a physical interface that appears to only exist to be the IP address of the gatekeeper. The 3700 router has other physical interfaces such as the serial interface to the WAN plus the gateway interface for the LAN.

The 10/100 interface with the gatekeeper IP address has no other configuration besides the "ip address" command. It is also physically connected to the switch.

All the gatekeeper unique configs are in the gatekeeper config on the 3700.

Do I really need to dedicate a physical interface so be the gatekeeper? Can I usa loopback interface or use my gateway ip address?

Thank you.

You can actually use interface you like as long matches your GWs configuration.

Re: Do gatekeepers need a dedicated physical interface

Thank you for the answer but what do you mean by "your GWs configuration?" I assume GW=Gateway.

Just that whatever reference to addresses, must match.

Re: Do gatekeepers need a dedicated physical interface

We've redeployed out gatekeeper using /32 loop back interfaces.  We have 2 routers each with a /32 loop back.  Then we have 1 gatekeeper on each router configred in a cluster with each other.  It works great.   Now we can use that physical interface for something else and we have redundancy.

Thanks for the input.
