192.168.10.0/24 RIP 100 1 10.214.20.2 Vlan20
As shown in the displayed information above, MCE has obtained the routes of VPN2 through RIP,
and maintains these routes in a routing table different from the routing table for routing information
of VPN1 to the network segment 192.168.0.0, thus isolating the routes of VPN1 from the routes of
VPN2.

Configure the routing protocol running between the MCE and a PE
# MCE uses GigabitEthernet 2/0/3 to connect to GigabitEthernet 2/0/18 of PE. Configure the two
ports to be trunk ports and permit tagged packets of VLAN 30 and VLAN 40.
