Sample hub-and-spoke VPRN configuration

Sample hub-and-spoke VPRN

In a hub-and-spoke VPRN, the majority of the traffic is exchanged between the hub (for example, headquarters) and spoke sites (for example, branches). Traffic between spoke sites passes through the hub site. Spoke sites advertise their routes to the hub site, which in turn advertises these routes to the other spoke sites.

The following figure shows a sample hub-and-spoke VPRN service configuration. Your configuration will vary depending on your network requirements.

Configuration steps

Assuming the core IP/MPLS or GRE network is already configured, the following table high-level tasks are required to configure this sample hub-and-spoke VPRN service.

1	Configure policies as required, for example, access ingress and egress, Routing, Scheduler, ACL IP, Accounting, ANCP, and DoS protection.
2	Configure ports as access ports for use in the service.
3	Configure service tunnels as required.
4	Configure MP-BGP for PE-to-PE routing.
5	Create and configure customers.
6	Create and configure VPRN 1.
