Configuration Roadmap
The configuration roadmap is as follows:
1. Configure OSPF on the backbone routers (PE1, PE2, and PE3) to implement interworking
of these backbone routers.
2. Enable MPLS capability on the MPLS backbone and establish an LDP LSP.
3. Configure a VPN instance on PE1, PE2, and PE3 and connect CE1 to PE2 and PE3.
4. Establish EBGP adjacencies between the PEs and CE1 and import VPN routes. Establish
MP-IBGP adjacencies between the PEs.
5. On PE1, configure a routing policy for VPN FRR, configure the backup next hop, and
enable VPN FRR. If the VPN FRR is not required, run the undo vpn frr command to
disable this function.
Data Preparation
To complete the configuration, you need the following data:
l Name of VPN instance, RD, and VPN target (111:1) on PE
l Name of the routing policy on PE1 and IP prefix
Procedure
Step 1 Configure the VLAN on each interface. The configuration procedure is not given here.
Step 2 Configure IP addresses of interfaces on the VPN backbone network and VPN sites. The
configuration procedure is not mentioned here.
Step 3 Configure OSPF on the MPLS backbone network to implement interworking of the PEs. The
configuration procedure is not mentioned here.
Step 4 Configure basic MPLS functions and MPLS LDP on the MPLS backbone network and set up
LDP LSPs.
NOTE
The PE devices are directly connected In this example, you need to run label advertise command to enables
the egress node to assign labels normally to the penultimate hop.
