The output shows that the static route of VPN 1 has been redistributed to the OSPF routing table of
PE 1.
Take similar procedures to configure OSPF process 20 between MCE and PE 1 and redistribute
VPN 2’s routing information from RIP into the OSPF routing table of MCE. The following output
shows that PE 1 has learned the private route of VPN 2 through OSPF.
<PE1> display ip routing-table vpn-instance vpn2

Now, the routing information of the two VPNs has been redistributed into the routing tables on PE 1.
Using BGP to advertise VPN routes to the PE
Network requirements
As shown in Figure 131, use an Ethernet switch as the MCE device. Advertise the VPN routes in site 1 and
site 2 to PE 1, so that a VPN’s sites across the MPLS backbone network can communicate with each other
normally.
Use OSPF in both site 1 and site 2. Use EBGP between the MCE and PE 1.
