transmission of data in the internal network, the company hopes to add the VPNs to the current
network, keeping the original VPN network independent.

Since company H accesses the Internet through carrier, if you connect company Z to the Internet
by renting PE from carrier, resources will be wasted. After feasibility analysis of the link from the
shared PE in city S to CE, VMCE is taken as the intermediate device to connect the two branches
in city S to the Internet.

Suppose that all the devices have been successfully configured as the following:

PE 1: The management IP address is 10.172.1.1/32. VRF instance vpnHub1 is associated
with the subinterface Eth1/0.1 of Eth 1/0, the Import RT is 1000:1 and Export RT is 1000:1;
VRF instance vpnHub2 is associated with the subinterface Eth1/0.2, the Import RT is 2000:1
and Export RT is 2000:1.

PE 2: The management IP address is 10.172.2.1/32, VRF instance vpnHub2 is associated
with interface Eth 4/0, the Import RT is 2000:1, and Export RT is 2000:1.

PE 3: The management IP address is 10.172.3.1/32, VRF instance vpnHub1 is associated
with interface Eth 6/0, the Import RT is 1000:1, and Export RT is 1000:1.

PE 4: The management IP address is 10.172.4.1/32, VRF instance vpnHub1 is associated
with interface Eth 4/0/1, the Import RT is 1000:1, and Export RT is 1000:1.

VMCE: The management IP address is 10.172.5.1/32. Eth 1/0, which belongs to VLAN 1,
VLAN 2, and VLAN 3 is connected to PE 1; Eth 1/1, which belongs to VLAN 2 is connected
to CE 1; Eth 1/3, which belongs to VLAN 3 is connected to CE 2.

CE 1: The management IP address is 10.172.6.1/32.

CE 2: The management IP address is 10.172.7.1/32.

CE 3: The management IP address is 10.172.8.1/32.

CE 4: The management IP address is 10.172.9.1/32.

CE 5: The management IP address is 10.172.10.1/32

Scenario analysis

As each branch has many access points, you can use MVM to create a special VPN group to
include all the VPNs in city B, city S, city N and city Z. As a result, you can manage all the networks
of the whole company. Suppose MVM the Import RT value of VPN instance vpnHub1 associated
with subinterface 1/0.1 on PE 1 is 2000:1, you can perform configuration audit for the device
through MVM to know changes of the VRF instance.
