3.17.10 Example for Configuring the OSPF Sham Link
Networking Requirements
As shown in Figure 3-12, CE1 and CE2 belong to the same OSPF area of vpn1 and are connected
to PE1 and PE2 respectively. Assume that the cost of each link is 1.
A CE and a PE communicate through OSPF. VPN traffic is forwarded between CE1 and CE2
over the MPLS backbone, not through the OSPF intra-area routes.
