Configuration Roadmap
The configuration roadmap is as follows:
1. Enable the routing protocol to ensure communication between the PEs.
2. Configure the basic MPLS capability on the PEs on the backbone network and set up an
LSP and two MPLS TE tunnels between the PEs.
3. Configure VPN instances on the PEs and connect the CEs to the PEs.
