Configuring Martini MPLS L2VPN
Martini MPLS L2VPN uses extended LDP to transfer Layer 2 information and VC labels. To configure
Martini MPLS L2VPN, you need to:
z
Create a Martini MPLS L2VPN connection
After you create a Martini MPLS L2VPN connection on a Layer 3 interface, packets received on the
interface will be forwarded through the connection.
z
Configure the remote peer PE
In Martini MPLS L2VPN implementation, VC labels need to be exchanged between PEs. As two PEs
may not be connected to each other directly, you need to establish a remote session between the two
PEs, so that VC FECs and VC labels can be transferred through the session.
Configuration Prerequisites
Before configuring Martini MPLS L2VPN, complete these tasks:
z
Configuring IGP on the PEs and P devices to guarantee the IP connectivity of the MPLS backbone
z
Configuring MPLS basic capability and MPLS LDP for the MPLS backbone on the PEs and P
devices to establish LDP LSPs
z
Enabling MPLS L2VPN on the PEs
z
Establishing remote LDP sessions between PEs
z
For VLAN access, configuring a subinterface; for ATM access, configuring a VC
To configure Martini MPLS L2VPN, you need the following data:
z
Types and numbers of the interfaces connecting the CEs
z
L2VC destination address and VC ID
z
Tunneling policy
Configuration Procedure
Follow these steps to configure Martini MPLS L2VPN on the PE:
