Configuring LDP PW redundancy
Network requirements
Create two LDP PWs to implement PW redundancy between CE 1 and CE 2. The primary PW goes
through PE 1—PE 2. The backup PW goes through PE 1—PE 3. When the primary PW fails, CE 1 and
CE 2 communicate through the backup PW.

Configuration procedure
Before you perform the following configurations, configure VLANs and add ports to VLANs on switches.
1. Configure CE 1:
system-view
[CE1] interface vlan-interface 10
[CE1-Vlan-interface10] ip address 100.1.1.1 24
[CE1-Vlan-interface10] quit
