have learned the routes to the loopback interfaces of each other. Verify that each ASBR-PE and the
PE in the same AS can ping each other. (Details not shown.)

Configure basic MPLS and enable MPLS LDP on each MPLS backbone to establish LDP LSPs:
# Configure basic MPLS on PE 1, and enable MPLS LDP for the interface connected to ASBR-PE 1.
<PE1> system-view
[PE1] mpls lsr-id 1.1.1.9
[PE1] mpls ldp
[PE1-ldp] quit
[PE1] interface vlan-interface 11
[PE1-Vlan-interface11] mpls enable
[PE1-Vlan-interface11] mpls ldp enable
[PE1-Vlan-interface11] quit
# Configure basic MPLS on ASBR-PE 1, and enable MPLS LDP for the interface connected to PE 1.
<ASBR-PE1> system-view
[ASBR-PE1] mpls lsr-id 2.2.2.9
[ASBR-PE1] mpls ldp
[ASBR-PE1-ldp] quit
[ASBR-PE1] interface vlan-interface 11
[ASBR-PE1-Vlan-interface11] mpls enable
[ASBR-PE1-Vlan-interface11] mpls ldp enable
[ASBR-PE1-Vlan-interface11] quit
# Configure basic MPLS on ASBR-PE 2, and enable MPLS LDP for the interface connected to PE 2.
<ASBR-PE2> system-view
[ASBR-PE2] mpls lsr-id 3.3.3.9
[ASBR-PE2] mpls ldp
[ASBR-PE2-ldp] quit
[ASBR-PE2] interface vlan-interface 11
[ASBR-PE2-Vlan-interface11] mpls enable
[ASBR-PE2-Vlan-interface11] mpls ldp enable
[ASBR-PE2-Vlan-interface11] quit
# Configure basic MPLS on PE 2, and enable MPLS LDP for the interface connected to ASBR-PE 2.
<PE2> system-view
[PE2] mpls lsr-id 4.4.4.9
[PE2] mpls ldp
[PE2-ldp] quit
[PE2] interface vlan-interface 11
[PE2-Vlan-interface11] mpls enable
[PE2-Vlan-interface11] mpls ldp enable
[PE2-Vlan-interface11] quit
# Each PE and the ASBR-PE in the same AS can establish an LDP neighbor relationship. Execute the
display mpls ldp peer command on the switches to verify that the session status is Operational.
(Details not shown.)
3.
Configure a VPN instance on the PEs:
For the same VPN, the route targets for the VPN instance on the PE must match those for the VPN
instance of the ASBR-PE in the same AS. This is not required for PEs in different ASs.
# Configure CE 1.
