I have a 7206VXR/NPE400 with a PA-T3 module in it.
I'm trying to put a loopback up towards the service provider so that they can do head-to-head testing. In interface configuration mode, I issue a 'loopback network line' command, but the provider tells me they never see the loop. I have also tried 'loopback network payload', with no luck.
Anyone have a clue why this is? I have done ' loopback local' and it works fine, I've tested to the loop.
