Configuration Roadmap
The configuration roadmap is as follows:
1. Configure the MPLS network to make the network layer reachable.
2. On the AC interface of PE1, configure PW1 (from PE1 to PE2) and PW2 (from PE1 to
PE3). PW1 functions as the master PW and PW2 functions as the backup PW.
3. Configure BFD sessions to check the connectivity of PW1 and PW2.
Data Preparation
To complete the configuration, you need the following data:
l IP addresses of the interfaces, including VLAN interfaces and VLANIF interfaces
l VC-ID of the PW
l BFD session name, local discriminator, and remote discriminator
Procedure
Step 1 Configure interface addresses for CE, PE,and P according to Figure 6-16, including VLAN and
VLANIF interfaces.
The configuration procedure is not mentioned.
Step 2 Configure an IGP protocol on the MPLS backbone network so that PEs and P can interwork.
The configuration procedure is not mentioned.
After the configuration, run the display ip routing-table command on the PEs, and you can see
that PE1 and PE2, and PE1 and PE3 have learned the routes on the Loopback1 interface of each
other.
Take the display on PE1 for example.
