The output shows that the MCE has learned the private routes of VPN 2. The MCE maintains the
routes of VPN 1 and those of VPN2 in two different routing tables. In this way, routes from different
VPNs are separated.
3. Configure routing between MCE and PE 1:
# The MCE uses port GigabitEthernet 1/0/3 to connect to PE's port GigabitEthernet 1/0/1.
Configure the two ports as trunk ports, and configure them to permit packets carrying VLAN tags
30 and 40 to pass.
[MCE] interface gigabitethernet 1/0/3
[MCE-GigabitEthernet1/0/3] port link-type trunk
[MCE-GigabitEthernet1/0/3] port trunk permit vlan 30 40

# Configure GigabitEthernet1/0/1 on the PE.

[PE1-GigabitEthernet1/0/1] port link-type trunk
[PE1-GigabitEthernet1/0/1] port trunk permit vlan 30 40
[PE1-GigabitEthernet1/0/1] quit
# On the MCE, create VLAN 30 and VLAN-interface 30, bind the VLAN interface with VPN
instance vpn1, and configure an IP address for the VLAN interface.
