C 10.10.30.0/24 is directly connected, VLAN 30
C 10.10.30.2/32 is local host.
O 10.10.60.0/24 [110/2] via 10.10.30.3, 00:02:42, VLAN 30
C 192.168.20.0/24 is directly connected, FastEthernet 0/23

C 10.10.30.0/24 is directly connected, VLAN 30
C 10.10.30.3/32 is local host.
C 10.10.60.0/24 is directly connected, VLAN 60
C 10.10.60.1/32 is local host.
O 192.168.20.0/24 [110/2] via 10.10.30.2, 00:01:36, VLAN 30
From the above information, we can learn that MCE has learned the
private-network routes in VPNc through OSPF, and maintains the routing
information of VPNa and VPNb in three different routing tables, effectively
accomplishing VPN isolation and allowing the use of overlapped addresses in
different VPNs.

C 10.10.60.0/24 is directly connected, VLAN 60
C 10.10.60.2/32 is local host.
O 192.168.20.0/24 [110/3] via 10.10.60.1, 00:00:00, VLAN 60
From the above information, we can learn that routing information of VPNc
instance has been fully propagated to PE.
