Procedure
Step 1 Configure IGP to implement the inter-networking between the Hub-PE and the Spoke-PE in the
backbone network.
The OSPF is used in this example, and the specific configuration procedures are not mentioned.
After the configuration, the OSPF neighbor relationship is established between each pair of Hub-
PE and Spoke-PE.
After running the display ospf peer command, you can see that the status of the neighbor is
Full.
After running the display ip routing-table command on the PE, you can find that PEs learn the
Lookback routes of each other.
Step 2 Configure the basic MPLS capabilities and MPLS LDP on the backbone networks and establish
LDP LSP.
The specific configuration procedures are not mentioned here.
After the configuration, LDP neighbor relationship is established between the Hub-PE and the
Spoke-PE.
After running the display mpls ldp session command on each device, you can see that the status
of the session is "Operational".
Step 3 Configure VPN instances on each PE and connect the CE to the PE.
# Configure Spoke-PE 1.

[Spoke-PE2-vpn-instance-vpna-af-ipv4] quit
[Spoke-PE2-vpn-instance-vpna] quit
[Spoke-PE2] interface ethernet 1/0/0
Issue 01 (2012-04-20)
MPLS LSR IDs on the PEs
The VPN instance name of the Hub-PE and Spoke-PE, RD and the VPN-target
NOTE
The Import-Target list of one of the VPN on Hub-PE should include the Export-Targets of all Spoke-PEs.
The Export-Target list of another VPN on Hub-PE should include the Import-Targets of all Spoke-PEs.
