Configuration procedure
1. Configure an IGP on the MPLS backbone to ensure IP connectivity within the backbone:
This example uses OSPF. (Details not shown.)
After the configurations, OSPF adjacencies are established between PE 1, P, and PE 2.
Execute the display ospf peer command. The output shows that the adjacency status is Full.
Execute the display ip routing-table command. The output shows that the PEs have learned
the loopback route of each other.
2. Configure basic MPLS on the PEs:
# Configure PE 1.
<PE1> system-view
[PE1] mpls lsr-id 1.1.1.9
[PE1] mpls
[PE1-mpls] quit
# Configure PE 2.
<PE2> system-view
[PE2] mpls lsr-id 2.2.2.9
[PE2] mpls
[PE2-mpls] quit
3. Configure VPN instances on PEs to allow CEs to access, and apply tunneling policies to the
VPN instances, using a GRE tunnel for VPN packet forwarding:
# Configure PE 1.
[PE1] tunnel-policy gre1
[PE1-tunnel-policy-gre1] tunnel select-seq gre load-balance-number 1
