VSI Cannot Go Up in Martini VPLS Mode

VSI Cannot Go Up in Martini VPLS Mode

Fault Symptom

After Martini VPLS is configured, the VSI cannot go Up.

Procedure

  1. Run the display vsi name vsi-name command to check whether the encapsulation types on both ends are the same.

    • If the encapsulation types on both ends are different, run the encapsulation { ethernet | vlan } command in the VSI view to change the encapsulation type on one end to ensure that the two ends use the same encapsulation type.

    • If the encapsulation types on both ends are the same, go to step 2.

    NOTE:

    A VSI can be Up only when encapsulation types configured on both ends are the same.

  2. Run the display vsi name vsi-name command to check whether MTUs of the two ends are the same.

    • If MTUs of the two ends are different, run the mtu mtu-value command in the VSI view to change the MTU on one end to ensure that the two ends use the same MTU.

    • If MTUs of the two ends are the same, go to step 3.

    NOTE:

    A VSI can be Up only when MTUs configured for the two ends are the same.

  3. Run the display vsi name vsi-name verbose command to check whether VSI IDs or negotiation IDs on both ends are the same.

    • If VSI IDs or negotiation IDs on the two ends are different, run the vsi-id vsi-id command in the VSI-LDP view to change the VSI ID on one end, or run the peer peer-address [ negotiation-vc-id vc-id ] command to change the negotiation ID on one end to ensure that VSI IDs or negotiation IDs on the two ends are the same.

    • If the VSI IDs or negotiation IDs on both ends are the same, go to step 4.

  4. Run the display vsi name vsi-name verbose command to check whether the LDP session is Up.

    • If the LDP session is Down, see "LDP Session Goes Down" to make the LDP session go Up.

    • If the LDP session is Up, go to step 5.

    NOTE:

    The two ends can perform L2VPN negotiation only after the LDP session is Up.

  5. Run the display vsi name vsi-name verbose command to check whether the AC interfaces on both ends are Up.

    If the AC interfaces on the two ends are Down, see "Physical Interconnection&Interface Type" to make the AC interfaces go Up.
