way, Layer 2 protocol packets of different user networks can be transparently transmitted
on the backbone network, and VLAN IDs of the carrier are saved.
11.3 Configuring Interface-based Layer 2 Protocol
Transparent Transmission
When each interface of a device on the backbone network is connected to only one user network
and Layer 2 protocol packets sent from the user network do not need VLAN tags, you can
configure interface-based Layer 2 protocol transparent transmission so that Layer 2 protocol
packets can be transparently transmitted on the backbone network.
11.3.1 Establishing the Configuration Task
Applicable Environment
When each interface of a device on the backbone network is connected to only one user network
and Layer 2 protocol packets sent from the user network do not need VLAN tags, you can
configure interface-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 interface-based Layer 2 protocol transparent transmission, complete the
following tasks:
l Connecting interfaces correctly
l Configuring VLANs on Layer 2 interfaces
Data Preparation
To configure interface-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 the user-side interfaces on PEs and their default VLANs
