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 68. (Details not shown.)
# Verify that CE 1 and CE 2 c
an learn the OSPF route to the Ethernet interface of each other.

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