Configuring an MPLS L2VPN Connection Based on Layer 2 Ethernet 
Interface and VLAN 
 
 
At present, an MPLS L2VPN connection based on Layer 2 Ethernet interface and VLAN supports only 
LDP signaling negotiation, that is, only the Martini method support establishing MPLS L2VPN 
connection based on Layer 2 Ethernet interface and VLAN. 
 
If you create a Martini MPLS L2VPN connection on a VLAN interface, all packets carrying the VLAN tag 
will be forwarded through the connection, regardless of the Layer 2 Ethernet ports receiving the packets. 
This not only wastes the Layer 2 Ethernet interface and VLAN resources, but also cannot differentiate 
users and services connected to different Layer 2 Ethernet interfaces. 
MPLS L2VPN connections based on Layer 2 Ethernet interface and VLAN can solve the above 
problems. Such connections forward packets based on the inbound Layer 2 Ethernet interfaces and the 
VLAN tags in the packets. In other words, only packets that are received on the same Layer 2 Ethernet 
interface and carry the same VLAN tag are forwarded through the same MPLS L2VPN connection. 
To configure a connection based on Layer 2 Ethernet interface and VLAN, you need to create a service 
instance on the Layer 2 Ethernet interface, configure a packet matching rule for the service instance, 
and create a Martini MPLS L2VPN connection. After these configurations, packets that arrive at the 
Layer 2 Ethernet interface and match the packet matching rule will be forwarded through the created 
MPLS L2VPN connection. 
Configuration Prerequisites 
Before configuring an MPLS L2VPN connection based on Layer 2 Ethernet interface and VLAN, 
complete these tasks: 
Configuring IGP on the PEs and P devices to guarantee the IP connectivity of the MPLS backbone 
Configuring MPLS basic capability and MPLS LDP for the MPLS backbone on the PEs and P 
devices to establish LDP LSPs 
Enabling MPLS L2VPN on the PEs 
To configure an MPLS L2VPN connection based on Layer 2 Ethernet interface and VLAN, you need the 
following data: 
Types and numbers of the interfaces connecting the CEs
