(Optional) Defining Characteristic Information About a Layer 2 Protocol

(Optional) Defining Characteristic Information About a Layer 2 Protocol


When non-standard Layer 2 protocol packets with a specified multicast destination MAC address need to be transparently transmitted on the backbone network, define characteristic information about the Layer 2 protocol on the PE. The characteristics of the Layer 2 protocol include the protocol name, Ethernet encapsulation format, destination MAC address, and MAC address that replaces the destination MAC address of Layer 2 protocol packets.

When defining characteristic information about a Layer 2 protocol, do not use the following multicast MAC addresses to replace the destination MAC address of Layer 2 protocol packets:

  • Destination MAC addresses of BPDUs: 0180-C200-0000 to 0180-C200-002F
  • Destination MAC address of Smart Link packets: 010F-E200-0004
  • Special multicast MAC addresses: 0100-0CCC-CCCC and 0100-0CCC-CCCD
  • Common multicast MAC addresses that have been used on the device

Perform the following operations on PEs.


  1. Run system-view

    The system view is displayed.

  2. Run l2protocol-tunnel user-defined-protocol protocol-name protocol-mac protocol-mac [ encap-type { { ethernetii | snap } protocol-type protocol-type-value | llc dsap dsap-value ssap ssap-value } ] group-mac { group-mac | default-group-mac }

    Characteristic information about a Layer 2 protocol is defined.

  3. Run commit

    The configuration is committed.
