Cisco 7600 VPLS Configuration Help

At my shop we're trying to setup VPLS on our Cisco 7600 series (Yes they are EOL as fuck but support is still good and cheap spare parts are aplenty). We use OSPF for our MPLS core and already just do straight L2 xconnects so VPLS didn't seem that far off of a dream. Unfortunately that dream has seemed to died.

I'm setting up between three 7600's to create this tunnel with the following:

7600 1.1.1.1 l2 vfi Phones manual vpn id 231 neighbor 1.1.1.3 encapsulation mpls neighbor 1.1.1.6 encapsulation mpls 

7600 1.1.1.6 l2 vfi Phones manual vpn id 231 neighbor 1.1.1.3 encapsulation mpls neighbor 1.1.1.1 encapsulation mpls

7600 1.1.1.3 l2 vfi Phones manual vpn id 231 neighbor 1.1.1.1 encapsulation mpls neighbor 1.1.1.6 encapsulation mpls 

On each 7600 we have this in the interface VLAN config:

interface Vlan231 description Phones no ip address xconnect vfi Phones end 

Then we trunk that out to the ports needed as a standard VLAN. The Xconnect comes up and everything shows fine that I can diag.

1.1.1.1_7609#show mpls l2transport vc 231 Local intf Local circuit Dest address VC ID Status ------------ -------------------- --------------- ---------- ---------- VFI Phones VFI 1.1.1.3 231 UP VFI Phones VFI 1.1.1.6 231 UP 1.1.1.1_7609#show vfi name Phones Legend: RT=Route-target, S=Split-horizon, Y=Yes, N=No VFI name: Phones_DVS, state: up, type: multipoint VPN ID: 231 Local attachment circuits: Vlan231 Neighbors connected via pseudowires: Peer Address VC ID S 1.1.1.3 231 Y 1.1.1.6 231 Y 

Now on the switches at each location, we've tried running a ping between but getting failures. Also if I throw a VLAN on the int vlan on two of the 7600's, it fails to reach the other 7600.

Any ideas and suggestions would be appreciated, thank you!
