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.

# On the MCE, bind VLAN-interface 30 to VPN instance
vpn1
, and configure an IP address for
the VLAN interface.
