Before you perform the following configurations, configure VLANs and add ports to VLANs.
1. Configure CE 1.
<CE1> system-view
[CE1] interface gigabitethernet 1/0/1
[CE1-GigabitEthernet1/0/1] port link-type trunk
[CE1-GigabitEthernet1/0/1] port trunk permit vlan 10
[CE1-GigabitEthernet1/0/1] 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
[PE1] mpls lsr-id 192.2.2.2
# Enable L2VPN.
[PE1] l2vpn enable
# Enable global LDP.
[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 for LDP to create LSPs.
[PE1] ospf
[PE1-ospf-1] area 0
[PE1-ospf-1-area-0.0.0.0] network 10.1.1.1 0.0.0.255
[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
[PE1-ospf-1] quit
# Create VLAN 10 and assign GigabitEthernet 1/0/1 to the VLAN.
[PE1] vlan 10
[PE1-vlan10] port gigabitethernet 1/0/1
[PE1-vlan10] quit
# Create Ethernet service instance 10 on GigabitEthernet 1/0/1 to match packets that have an
outer VLAN ID of 10.
[PE1] interface gigabitethernet1/0/1
[PE1-GigabitEthernet1/0/1] service-instance 10
[PE1-GigabitEthernet1/0/1-srv10] encapsulation s-vid 10
[PE1-GigabitEthernet1/0/1-srv10] quit
[PE1-GigabitEthernet1/0/1] quit
# Create a cross-connect group named vpna, create a cross-connect named ldp in the group,
and bind Ethernet service instance 10 on GigabitEthernet 1/0/1 to the cross-connect.
[PE1] xconnect-group vpna
