Configuration procedure
1. Configure OSPF on the customer networks:
Configure conventional OSPF on CE 1, Router A, and CE 2 to advertise segment addresses of the
interfaces as shown in Figure 647. (Details not shown.)
After
completing the configurations, CE 1 and CE 2 can learn the OSPF route to the Ethernet
interface of each other. Take CE 1 as an example:

2. Configure MPLS L3VPN on the backbone:
# Configure basic MPLS and MPLS LDP on PE 1 to establish LDP LSPs.
