The output shows that the MCE has learned the private route of VPN 1 through OSPF process 10.
# On MCE, bind OSPF process 20 with VPN instance vpn2 to learn the routes of VPN 2. The
configuration procedure is similar to that for OSPF process 10.
The following output shows that the MCE has learned the private route of VPN 2 through OSPF:

Configure routing between the MCE and PE 1.
# Configure the connecting ports between the MCE and PE 1 as trunk ports. The configuration procedure
is similar to that described in “
Using OSPF to advertise VPN routes to the PE
.” (Details not shown)
# Start BGP process 100 on the MCE, and enter the IPv4 address family view of VPN instance vpn1.

# Specify PE 1 as the eBGP peer of the MCE, and redistribute the routing information of OSPF process
10. (The IP address of PE 1’s interface bound with VPN instance vpn1 is 10.100.10.3, and the BGP
process is 200.)
