Configuring OSPF sham links

Network requirements
CE 1 and CE 2 belong to VPN 1 and are connected to PE 1 and PE 2, respectively.
CE 1 and CE 2 are in the same OSPF area.
VPN traffic between CE 1 and CE 2 is required to be forwarded through the MPLS backbone, instead
of any route in the OSPF area.

Configure conventional OSPF on CE 1, Router A, and CE 2 to advertise segment addresses of
the interfaces as shown in
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:
