z 

An MCE device connects to VPN1 (with the address range being 192.168.0.0/16) through 

VLAN-interface 10 (with the IP address being 10.214.10.3) and connects to VPN2 (with the 

address range being 192.168.10.0/24) through VLAN-interface 20 (with the IP address being 

10.214.20.3). VPN2 has RIP enabled.  

z 

The MCE device connects to the PE through VLAN-interface 30 and VLAN-interface 40, whose IP 

addresses are 192.168.30.1/30 and 192.168.40.1/30, respectively.  

z 

It is required that the MCE device isolates routes of VPN1 from those of VPN2 and advertises all 

the VPN routes to the PE device using OSPF.

For distinguish devices, assume the system name of the MCE device is “MCE”, the names of the egress 

router of VPN1 and VPN2 are “VR1” and “VR2”, and the system name of the PE device is “PE”.
