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 ten-gigabitethernet 1/0/1
[CE1-Ten-GigabitEthernet1/0/1] port link-type trunk
[CE1-Ten-GigabitEthernet1/0/1] port trunk permit vlan 10
[CE1-Ten-GigabitEthernet1/0/1] quit
2. Configure PE 1:
# Configure an LSR ID.
system-view
[PE1] interface loopback 0
[PE1-LoopBack0] ip address 192.2.2.2 32
[PE1-LoopBack0] quit
[PE1] mpls lsr-id 192.2.2.2
# Enable L2VPN.
[PE1] l2vpn enable
# Enable LDP globally.
[PE1] mpls ldp
[PE1-ldp] quit
# Configure VLAN-interface 20 (the interface connected to P), and enable LDP on the interface.
