Network requirements
As shown in Figure 80 :
• 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.
