CallManager express

has anyone configured cme using th loopback interface?

As sample config would be nice.

When I try to setup the fast ethernet ie: fa0/0.200 using the same subnet the 3725 says the ip address overlaps the loopback address.

For example loopback 0 10.10.10.20 /24

fastethernet 0/0.200 10.10.10.50/24

Set your loopback to /32.

Re: CallManager express

Thanks but I am a little confused here. If I use a 32 which is what I thought of how do I route packets to that address.

Do I need to set a route to the loopback or ?

I think I have tought of this too much and got myself confused.

I trunk the the 3725 to a 3550 but but how is the loopback address known.

Hope this makes sense as I am confuse now

With routing. Include the if.s in routing and all your routers will know about them.
