Configuration Roadmap
The configuration roadmap is as follows:
1. Configure VPN instances on the PEs on the backbone network. Bind the interfaces
connected to CEs to the corresponding VPN instances so that CE1 and CE2 belong to a
VPN instance, and CE3 and CE4 belong to another VPN instance. Then assign IP addresses
to the PE interfaces connected to CEs.
2. Configure OSPF on the PEs to implement interconnection between PEs.
3. Enable MPLS and MPLS LDP on the PEs and P and set up an MPLS LSP.
