Scenario analysis

The headquarter requires that the branches cannot communicate with one another, but can
communicate with the headquarter. To achieve this purpose, Hub-Spoke networking scheme is
adopted. CE 1 is the headquarter of the company, that is, it is the hub site; CE 2, CE 3 and CE 4
are the three branches, that is, they are spoke sites.

Suppose that the BGP/MPLS VPN backbone where the PEs reside has been established and the
MPLS function has been enabled on the PEs and PE interfaces. To implement hub-spoke networking,
you need to perform the following configurations:

PE 1: The management IP address is 10.172.152.1/32, VRF instance vpnHub is associated
with interface Eth 4/1, RD is 10.172.152.1:1001, Import RT is 100:1, Export RT is 100:2
and AS number is 65001.

PE 2: The management IP address is 10.172.152.2/32, VRF instance vpnSpoke is associated
with interface Eth 1/0, RD is 10.172.152.2:1001, Import RT is 100:2, Export RT is 100:1
and AS number is 65001.

PE 3: The management IP address is 10.172.152.3/32, VRF instance vpnSpoke is associated
with interface Eth 2/0, RD is 10.172.152.3:1001, Import RT is 100:2, Export RT is 100:1
and AS number is 65001.

PE 4: The management IP address is 10.172.152.4/32, VRF instance vpnSpoke is associated
with interface Eth 2/0, RD is 10.172.152.4:1001, Import RT is 100:2, Export RT is 100:1
and AS number is 65001.

CE 1: The management IP address is 10.172.153.1/32.

CE 2: The management IP address is 10.172.153.2/32.

CE 3: The management IP address is 10.172.153.3/32.

CE 4: The management IP address is 10.172.153.4/32.
