Configuration procedure
1. On CE 1, configure the link protocol type as PPP on Serial 2/0 (the interface connected to the PE
1), and configure an IP address for the interface.
<Sysname> system-view
[Sysname] sysname CE1
[CE1] interface serial 2/0
[CE1-Serial2/0] link-protocol ppp
[CE1-Serial2/0] ip address 100.1.1.1 24
2. Configure PE 1:
# Configure the LSR ID and enable MPLS globally.
<Sysname> system-view
[Sysname] sysname PE1
[PE1] interface loopback 0
[PE1-LoopBack0] ip address 192.2.2.2 32
[PE1-LoopBack0] quit
[PE1] mpls lsr-id 192.2.2.2
[PE1] mpls
[PE1-mpls] quit
# Enable MPLS LDP globally.
[PE1] mpls ldp
[PE1-mpls-ldp] quit
# Configure PE 1 to establish a remote LDP session with PE 2.
[PE1] mpls ldp remote-peer 1
[PE1-mpls-ldp-remote-1] remote-ip 192.3.3.3
[PE1-mpls-ldp-remote-1] quit
# Configure Serial 2/1, the interface connected to the P device, and enable LDP on the interface.
[PE1] interface serial 2/1
[PE1-Serial2/1] link-protocol ppp
[PE1-Serial2/1] ip address 10.1.1.1 24
[PE1-Serial2/1] mpls
[PE1-Serial2/1] mpls ldp
[PE1-Serial2/1] quit
# Configure OSPF on PE 1.

[PE1-ospf-1-area-0.0.0.0] network 192.2.2.2 0.0.0.0
[PE1-ospf-1-area-0.0.0.0] quit
