Configuring IP interworking over an LDP PW
Network requirements
CE 1 and PE 1 are connected through Ethernet interfaces. CE 2 and PE 2 are connected through serial
interfaces, and they use PPP as the link layer protocol.
Configure an LDP PW between PE 1 and PE 2 and enable interworking on PEs so GigabitEthernet 2/1/1
on CE 1 can communicate with Serial 2/1/0 on CE 2.

Configuration procedure
1. Configure CE 1.
<CE1> system-view
[CE1] interface gigabitethernet 2/1/1
[CE1-GigabitEthernet2/1/1] ip address 100.1.1.1 24
[CE1-GigabitEthernet2/1/1] quit
2. Configure PE 1:
# Configure an LSR ID.
<PE1> system-view
[PE1] interface loopback 0
[PE1-LoopBack0] ip address 192.2.2.2 32
[PE1-LoopBack0] quit
