Method and apparatus for implementing hub-and-spoke topology virtual private networks
Deployment of a hub-and-spoke (HaSP) topology virtual private network (VPN) may be facilitated by implementing a bi-directional VRF on a hub PE and using the hub PE as a hub-reflector. Route distinguishers and route targets may be used to differentiate traffic originating on the spokes from traffic originating on the hub. Using a bi-directional VRF allows a HaSP VPN to be created using a single link between the hub CE and hub PE. Allowing the hub CE to control spoke route distribution, and differentiating the direction of the flow by route target and route designator, enables the hub to control traffic between the spokes. Configuring the hub PE as a route reflector allows communication between the spokes to take place without having the CE hub inspect every piece of traffic. Optionally, other services may be provided by the hub PE as well, such as NAT, firewall, and AAA services.
