[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

Configure PE 1:
# Configure an LSR ID.

system-view

[PE1] interface loopback 0

[PE1-LoopBack0] ip address 192.2.2.2 32

[PE1] mpls ldp

[PE1-ldp] quit

# Configure VLAN-interface 20 connected to the P device and enable LDP on the interface.

[PE1] interface vlan-interface 20

[PE1-Vlan-interface20] ip address 10.1.1.1 24

[PE1-Vlan-interface20] mpls enable

[PE1-Vlan-interface20] mpls ldp enable

[PE1-Vlan-interface20] quit

# Configure OSPF on PE 1 for LDP to create LSPs.

[PE1] ospf

[PE1-ospf-1] area 0

VLAN ID of 10.

[PE1] interface ten-gigabitethernet1/0/1

[PE1-Ten-GigabitEthernet1/0/1] service-instance 10

[PE1-Ten-GigabitEthernet1/0/1-srv10] encapsulation s-vid 10

[PE1-Ten-GigabitEthernet1/0/1-srv10] quit

[PE1-Ten-GigabitEthernet1/0/1] quit

# Create a cross-connect group named vpna, create a cross-connect named svc in the group, and

bind service instance 10 on Ten-GigabitEthernet 1/0/1 to the cross-connect.
