MPLS routed pseudowire between ASR9k and 7600 with LAN cards

Hi,

There is a need to extend L2 connections from an existing 7600 with LAN cards to a new ASR9001 and configure IP address on that connection.

To my understanding this looks something like "Pseudowire Headend".

ASR9k:

l2vpn

xconnect group test

p2p test

interface PW-Ether555

neighbor 192.168.0.1 pw-id 555

interface PW-Ether555

mtu 9216

vrf MGMT

ipv4 address 172.30.2.1 255.255.255.252

attach generic-interface-list test

generic-interface-list test

interface Bundle-Ether1

interface TenGigE0/0/0/1

7600:

interface TenGigabitEthernet3/4.555

encapsulation dot1Q 555

xconnect 192.168.0.2 555 encapsulation mpls

mtu 9202

The problem here is that ASR thinks that everything is fine:

Group test, XC test, state is up; Interworking none

AC: PW-Ether555, state is up

Type PW-Ether

Interface-list: test

Replicate status:

Te0/0/0/1: success

BE1: success

MTU 9202; interworking none

Internal label: 16020

Statistics:

packets: received 0, sent 60

bytes: received 0, sent 2532

PW: neighbor

192.168.0.1

, PW ID 555, state is up ( established )

PW class not set, XC ID 0xc0000001

Encapsulation MPLS, protocol LDP

Source address 172.30.0.2

PW type Ethernet, control word disabled, interworking none

PW backup disable delay 0 sec

Sequencing not set

PW Status TLV in use

MPLS Local Remote

However at the same time 7600 is unhappy:

BIP-STO1#sh xconnect int te3/4.555 detail

Legend: XC ST=Xconnect State S1=Segment1 State S2=Segment2 State

UP=Up DN=Down AD=Admin Down IA=Inactive

SB=Standby HS=Hot Standby RV=Recovering NH=No Hardware

XC ST Segment 1 S1 Segment 2 S2

------+---------------------------------+--+---------------------------------+--

DN ac Te3/4.555:555(Eth VLAN) UP mpls 192.168.0.2:555 DN

Interworking: ethernet Local VC label 45

Remote VC label 16021

What am I missing here? Is this even the right approach to reach the goal?

I succeeded in a similar task where there was HP 5800 at the other end of L2 circuit. I used bridge domain, VPLS and BVI interface in that case. Unfortunately VPLS is not an option for 7600 with LAN cards.
