Run OSPF in both VPNs 1 and 2, and run EBGP between the MCE and PE 1. 21

The output shows that PE 1 has learned the private route of VPN 2 through OSPF.
Now, the routing information for the two VPNs has been redistributed into the VPN routing tables
on PE 1.
Using BGP to advertise VPN routes to the PE
Network requirements
As shown in
Figure 5
, 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 VPNs 1 and 2, and run EBGP between the MCE and PE 1.
