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:
# 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
[MCE-Vlan-interface30] ip address 30.1.1.1 24
[MCE-Vlan-interface30] quit
# Bind VLAN-interface 40 to VPN instance vpn2, and configure an IP address for the VLAN
interface.
[MCE] interface vlan-interface 40
