Configuration Roadmap
The configuration roadmap is as follows:
1. Run an IGP protocol on the backbone network so that the devices in the same AS can
communicate with each other.
2. 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.
3. Establish MPLS L2VC connections between the PEs and ASBR-PEs in the same AS.
Data Preparation
To complete the configuration, you need the following data:
l IS-IS data
l IP address of the peer
l MPLS LSR-IDs of PE and ASBR-PEs
l L2VC ID
Procedure
Step 1 Configure the IDs of the VLANs to which the interfaces belong according to Figure 5-10.
The configuration procedure is not mentioned.
Step 2 Configure an IGP protocol on the MPLS backbone network.
PEs and ASBR-PEs on the 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 ASBR and PE in the same AS can establish an IS-IS adjacency. Run
the display isis peer command, and you can see that the IS-IS adjacency is in Up state, and the
PEs can learn each other's loopback address.
Take the display on PE1 for example.
