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 the MCE and PE 1:
# The MCE uses port FortyGigE 1/0/3 to connect to PE's port FortyGigE 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 fortygige 1/0/3

[MCE-FortyGigE1/0/3] port link-type trunk

[MCE-FortyGigE1/0/3] port trunk permit vlan 30 40

[MCE-FortyGigE1/0/3] quit

# Configure port FortyGigE 1/0/1 on the PE.

[PE1] interface fortygige 1/0/1

[PE1-FortyGigE1/0/1] port link-type trunk

[PE1-FortyGigE1/0/1] port trunk permit vlan 30 40

[PE1-FortyGigE1/0/1] 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.

[MCE] vlan 30

# On the MCE, create VLAN 40 and VLAN-interface 40, bind the VLAN interface with VPN

, and configure an IP address for the VLAN interface.
