VPLS Connection Fault

VPLS Connection Fault

Fault Symptom

When a Huawei device connect to a non-Huawei device using VPLS, VPLS status is not Up.


  • Connecting to Juniper devices

    When a Huawei device connects to a Juniper device using Kompella VPLS, BGP peers are Down. The VPLS network cannot be established. Rectify the fault as follows:

    1. Configure the L2VPN address family as a unicast address family on a Juniper device.
    2. Set default-offset to 1 on the Huawei device. The CE ID cannot be 0.
  • Connecting to Cisco devices

    As defined by the latest RFC, the encapsulation type of PW in the Kompella VPLS is 19. Huawei devices support only the Ethernet encapsulation and VLAN encapsulation. When a Huawei device connects to a Cisco device using VPLS, VPLS status is not Up. Rectify the fault as follows:

    1. Run encapsulation rfc4761-compatible

      The encapsulation type for Kompella VPLS is configured to be in compliance with RFC 4761.

      Before a Kompella VPLS network sends packets with encapsulation types other than encapsulation type 19, the network converts the encapsulation types of these packets to encapsulation type 19.

      If a Kompella VPLS network receives packets with encapsulation type 19, the network automatically converts the encapsulation types of these packets to its own encapsulation type.

    2. Run mtu-negotiate disable

      The MTU match check is disabled.

      By default, the MTU value in the VSI view is 1500. If the MTUs for the same VSI on two PEs are different, the two PEs cannot exchange information or establish a connection.

      The equipment of some vendors cannot perform the MTU match check for VSIs. If a Huawei device needs to communicate with a non-Huawei device over a Kompella VPLS network, run the mtu-negotiate disable command to disable the MTU match check.
