Data Preparation
To complete the configuration, you need the following data:

Procedure
Step 1 Configure an IGP protocol on the backbone network to make the Hub-PE and the Spoke-PE
communicate with each other.
In this example, OSPF is used as IGP and the configuration procedure is not mentioned.
After configuration, an OSPF neighbor relation is set up between the PEs. Run the display ospf
peer command, and you can see that the neighbor relation is in Full state. Run the display ip
routing-table command on the PEs, and you can see that the PEs can learn the routes on the
loopback interface of each other.
Step 2 Configure the basic MPLS capability and MPLS LDP on the backbone network and set up an
LDP LSP.
The configuration details are not mentioned here.
After the configuration, LDP peer relation can be set up between the Hub-PE and the Spoke-
PEs. Run the display mpls ldp session command on each Switch, and you can see that the
session status is Operational.
Step 3 Configure the IPv6 VPN instances on each PE and connect the CEs to the PEs.

Set up tunnel and IBGP peer relation between the Hub-PE and the Spoke-PE. Do not set
up IBGP peer relation between Spoke-PEs because they do not exchange VPN routes.
Create two IPv6 VPN instances, namely, vpn_in and vpn_out, on the Hub-PE. The VPN
target received by vpn_in is the same as the VPN target advertised by the Spoke-PEs. The
VPN target advertised by vpn_out is different from the received VPN target, but is the
same as the VPN target received by the Spoke-PEs.
Create an IPv6 VPN instance on the Spoke-PE. The VPN target received by the IPv6 VPN
instance is the same as the VPN target advertised by vpn_out, and the VPN target advertised
by the IPv6 VPN instance is the same as the VPN target received by vpn_in.
Run BGP4+ between the CE and the PE.
Configure the Hub-PE to accept the routes in an AS whose number is repeated once.
MPLS LSR IDs of the PEs
VPN instance names, RDs, and VPN targets of the Hub-PE and Spoke-PE
NOTE
Pay attention to the VPN targets on the Hub-PE and Spoke-PE.
