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
[MCE-Vlan-interface30] ip binding vpn-instance vpn1

interface.

# Configure the IP address of the interface Loopback 0 as 101.101.10.1 for the MCE and as

PE 1. (Details not shown.)
