VLAN-based Layer 2 protocol transparent transmission so that Layer 2 protocol packets are
transparently transmitted on the backbone network.
11.4.1 Establishing the Configuration Task
Applicable Environment
When each interface of devices on the backbone network is connected to multiple user networks
and Layer 2 protocol packets sent from user networks contain VLAN tags, you can configure
VLAN-based Layer 2 protocol transparent transmission. In this way, Layer 2 protocol packets
from user networks are transmitted to destination user networks through different Layer 2 tunnels
on the backbone network to implement calculation of Layer 2 protocols.
Pre-configuration Tasks
Before configuring VLAN-based Layer 2 protocol transparent transmission, complete the
following task:
l Connecting interfaces correctly
Data Preparation
To configure VLAN-based Layer 2 protocol transparent transmission, you need the following
data.
No.
Data
1 Name of the user-defined protocol
2 Destination MAC address of Layer 2 protocol packets and multicast MAC address
that replaces the destination MAC address
3 Names of user-side interfaces on PEs and VLANs allowed by user-side interfaces
11.4.2 (Optional) Defining Characteristic Information About a
Layer 2 Protocol
Context
When non-standard Layer 2 protocol packets with a certain multicast destination address need
to be transparently transmitted on the backbone network, you can define characteristic
information about the Layer 2 protocol.
Do as follows on PEs.
