The routing information for the two VPNs has been redistributed into the routing tables on PE 1.
Configuring the MCE that uses EBGP to advertise VPN
routes to the PE
Network requirements
As shown in Figure 111, configure the MCE to advertise the routes of VPNs 1 and 2 to PE 1, so that
the sites of each VPN can communicate with each other over the MPLS backbone.
Run OSPF in both VPN 1 and VPN 2. Run EBGP between the MCE and PE 1.
