Procedure
Step 1 Configure OSPF on the MPLS backbone network to implement network connectivity.
After the configuration, an OSPF adjacency is set up among UPE, SPE, and PE. Run the display
ospf peer command, and you can see that the adjacency is in Full state. Run the display ip
routing-table command on the PEs, and you can see the PEs can learn the loopback routes of
each other.
The configuration procedure is not mentioned.
Step 2 Configure basic MPLS functions and MPLS LDP on the MPLS backbone network and set up
LDP LSPs.
After the configuration, LDP sessions are established between UPE and SPE, and between SPE
and PE. By running the display mpls ldp session command, you can see that the session status
is Operational. By running the display mpls ldp lsp command, you can see the establishment
status of the LDP LSP.
The configuration procedure is not mentioned.
Step 3 Connect PEs to CEs and run BGP between them.
