Re: Frustrated with VPLS problem. VC up but no traffic is

Hi Brian,

Thanks for the VPLS config. However,it's not the scenrio I want to run.

In the config I posted before some of the items from old config was left.
That's why you saw some irrelevant configs there. Here is the clean version.

in my case XR is head end with out any AC attacheded and it's terminating
2xPWs from R5 and R4. So the only thing that XR should do is learning MAC
addresses and advertise R5 traffic to R4 and vise versa.

As there is no AC attached to XR, it is core router rather than
edge.(Engine 3 line cards restriction shouldnt apply)

Ping mpls pseudowire 1.1.1.1 doesnt work from R4
Ping from 3550 int vlan 100 to ME3400 doesnt work.
sh l2vpn forwarding brid mac-add location Shows nothing. I cant see any
mac-address that is being learned.

Im really frustrated as I cant figure out this after 3 days doing that on
racks, 9-12 hours in last 2 days.
