(Optional) Configuring Huawei Devices to Communicate with Non-Huawei Devices

(Optional) Configuring Huawei Devices to Communicate with Non-Huawei Devices

Context

The latest RFC defines that the encapsulation type of PW in the Kompella VPLS is 19. Huawei devices support only the Ethernet encapsulation and VLAN encapsulation. When Huawei devices need to communicate with non-Huawei devices with the VPLS encapsulation type carried by BGP extended community attributes as 19, you need to set the global encapsulation type of Kompella VPLS on the Huawei device, and configure the Huawei device to ignore the MTU match check.

Do as follows on the PEs of the two ends of the PW:

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    mpls l2vpn

    The MPLS-L2VPN view is displayed.

  3. Run:

    vpls bgp encapsulation { ethernet | vlan }

    The global encapsulation type of Kompella VPLS is configured.

    After this command is used and the VPLS packet with encapsulation type 19 is received, the system re-encapsulates this packet according to the user configuration and then performs other processing related to VPLS.

    When this command is not used, the system re-encapsulates the received VPLS packet with encapsulation type 19 in VLAN mode.

    NOTE:

    The vpls bgp encapsulation { ethernet | vlan } and ignore-mtu-match commands must be used together on Huawei devices so that Huawei devices can communicate with non-Huawei devices.

  4. Run:

    quit

    The system view is displayed.

  5. Run:

    vsi vsi-name

    The view of the created VSI is displayed.

  6. Run:

    pwsignal bgp

    The VSI-BGP view is displayed.

  7. 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.

  8. 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.
