Configuration procedure
1. Configure IGP on the MPLS backbone to ensure connectivity within the backbone:
This example uses OSPF. (Details not shown.)
# Execute the display ospf peer command to verify that OSPF adjacencies in Full state have been
established between each ASBR-PE and the PE in the same AS, and that PEs have learned the
routes to the loopback interfaces of each other.
Each ASBR-PE and the PE in the same AS can ping each other.
2. Configure basic MPLS and MPLS LDP on the MPLS backbone to establish LDP LSPs:
# Configure basic MPLS on PE 1, and enable MPLS LDP on 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 on the interface connected to PE 1.
