S 192.168.10.0/24 [1/0] via 10.10.40.1
2) Display routing information of VPNb instance
View routing information on SwitchB (access device of VPNb site)
SwitchB#show ip route vrf vpnb
Routing Table: vpnb
C 10.10.20.0/24 is directly connected, VLAN 20
C 10.10.20.2/32 is local host.
R 10.10.50.0/24 [120/1] via 10.10.20.3, 00:01:20, VLAN 20
C 192.168.20.0/24 is directly connected, FastEthernet 0/23
C 192.168.20.1/32 is local host.
View routing information of VPNb instance on MCE device
MCE#show ip route vrf vpnb
Routing Table: vpnb
C 10.10.20.0/24 is directly connected, VLAN 20
C 10.10.20.3/32 is local host.
C 10.10.50.0/24 is directly connected, VLAN 50
C 10.10.50.1/32 is local host.
R 192.168.20.0/24 [120/1] via 10.10.20.2, 00:22:01, VLAN 20
From the above information, we can learn that MCE has learned the
private-network routes in VPNb, and maintains the routing information of VPNa
and VPNc in three different routing tables, effectively accomplishing VPN isolation
and allowing the use of overlapped addresses in different VPNs.

PE#show ip route vrf vpnb
Routing Table: vpnb
R 10.10.20.0/24 [120/1] via 10.10.50.1, 00:04:48, VLAN 50
C 10.10.50.0/24 is directly connected, VLAN 50
C 10.10.50.2/32 is local host.
R 192.168.20.0/24 [120/2] via 10.10.50.1, 00:02:15, VLAN 50
From the above information, we can learn that routing information of VPNb
instance have been fully propagated to PE.
3) Display routing information of VPNc instance
