[c-nsp] mpls on one interface carried over an l2tpv3 on another interface

[Joe Maimon]

Suppose I have a 7500 router with two fastethernets plugged into the 
same switch. 12.4 Mainline.

On fa0/0/0.2 I run mpls.

on Fa0/1/0.2 I run l2tpv3 xconnect to another identicaly setup router in 
another location.

(Yes, this is a workaround to an outage)

The l2tpv3 is up, BGP vpnv4 routes are up/advertised/received/imported.

Should I expect mpls to transport the vrf packets?

It doesnt, ping vrf XXX a.b.c.d, where a.b.c.d is on the other router, 
fails.

 From CCO

"For L2TPv3, an Ethernet subinterface configured to support VLAN 
switching may be bound to an Xconnect service so that all Ethernet 
traffic, tagged with a VID specified on the subinterface, is tunneled to 
another PE. The VLAN Ethernet frames are forwarded in their entirety. 
The receiving PE may rewrite the VID of the tunneled traffic to another 
value before forwarding the traffic onto an attachment circuit."

Thanks,

Joe
