Please find the attached topology i want the voice gateway to be registered with his loopback address and not by the gigabit interfaces, but it is registering with gigabit interface currently ,, do the below commands will help me to bind with loopback interface, i have not access the router CLI but Planning the single router with redundancy solutions.
mgcp bind control source-interface loopback0 mgcp bind media source-interface loopback0
Below is the plan
Will run eigrp on all the subnets ( between router and core A and between core B and router and between the core's also on the loopback
if gig0/0 link fails on the router loopback will be reachable through gig0/1 and the gateway will still be registered.
