[c-nsp] No Connectivity over Established X-Connect

[Steve McCrory]

Update:

I'm beginning to think it's a problem on the 7200 trying to bridge the
native vlan over a xconnect.

Has anyone run into such a problem or know of a potentially relevant
bug?

Thanks

Steven

Hi List,

 

I'm having a problem establishing connectivity over a point-to-point
x-connect. The endpoints for the x-connect are an ASR1004 running
15.0(1)S and a 7204VXR (NPE-G2) running 12.2(31)SB8. 

 

The x-connect is up and I can see ARP entry's on one side but not the
other. Apart from that there doesn't seem to be any other traffic
reaching either end.

 

When I run the command 'show mpls l2transport vc detail' I can see
packet drops on one side of the VC (the ASR) but not the other:

 

Router#sh mpls l2transport vc 1000 detail

Local interface: Gi0/2/4.1 up, line protocol up, Eth VLAN 1 up

  Destination address: 172.31.96.7, VC ID: 1000, VC status: up

    Output interface: Te0/1/0, imposed label stack {1367 150}

    Preferred path: not configured

    Default path: active

    Next hop: 172.31.100.37

  Create time: 00:04:26, last status change time: 00:04:26

  Signaling protocol: LDP, peer 172.31.96.7:0 up

    Targeted Hello: 172.31.96.55(LDP Id) -> 172.31.96.7, LDP is UP

    Status TLV support (local/remote)   : enabled/not supported

      LDP route watch                   : enabled

      Label/status state machine        : established, LruRru

      Last local dataplane   status rcvd: No fault

      Last local SSS circuit status rcvd: No fault

      Last local SSS circuit status sent: No fault

      Last local  LDP TLV    status sent: No fault

      Last remote LDP TLV    status rcvd: Not sent

      Last remote LDP ADJ    status rcvd: No fault

    MPLS VC labels: local 602, remote 150

    Group ID: local 0, remote 0

    MTU: local 4470, remote 4470

    Remote interface description: test

  Sequencing: receive disabled, send disabled

  Control Word: On (configured: autosense)

  VC statistics:

    transit packet totals: receive 0, send 41

    transit byte totals:   receive 0, send 5360

    transit packet drops:  receive 1457, seq error 0, send 0

 

Does anyone know of a reason why I'm seeing packet drops on the VC?

 

Thanks

 

Steven
