Data Preparation
To complete the configuration, you need the following data:

Procedure
Step 1 Configure the IDs of the VLANs to which the interfaces belong according to
The configuration procedure is not mentioned.
Step 2 Configure an IGP protocol on the MPLS backbone network.
PEs and ASBR-PEs on the MPLS backbone network can communicate with each other by using
IGP.
In this example, IS-IS is used as IGP and the configuration procedure is not mentioned.
After the configuration, the IS-IS neighbor relation can be established between the ASBR-PE
and the PE in the same AS. Run the display isis peercommand, and you can find that the neighbor
relation is Up.
Take the display on ASBR-PE1 for example.
<ASBR-PE1> display isis peer
System Id
0000.0000.0001
Total Peer(s): 1
Run the display ip routing-table command, and you can see that the PEs and ASBR-PEs can
learn the loopback routes of each other.
Take the display on ASBR-PE1 for example.
<ASBR-PE1> display ip routing-table

Issue 01 (2011-07-15)
Run an IGP protocol on the backbone network so that the devices in the same AS can
communicate with each other.
Configure the basic MPLS capability on the backbone network and establish dynamic LSPs
between PEs and ASBR-PEs in the same AS. If PEs and ASBR-PEs are not directly
connected, establish a remote LDP session.
Establish MPLS L2VC connections between the PEs and ASBR-PEs in the same AS.
