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.

Configure routing between the MCE and PE 1:
# On the MCE, bind VLAN-interface 30 to VPN instance vpn1, and configure an IP address for the
VLAN interface.
[MCE] interface vlan-interface 30
