ABSTRACT:
A method, apparatus and computer program product for providing dynamic routing support for Half-Duplex Virtual Routing and Forwarding (HDVRF) environments. The method, apparatus and computer program function to configure a forwarding Virtual Routing and Forwarding (VRF) table for a router with information to forward incoming packets to a central location within a hub and spoke environment. The method, apparatus and computer program also function to populate a routing Virtual Routing and Forwarding (VRF) table for the router with routing information received from ingress interfaces of the router. The method, apparatus and computer program function further forwards packets received on egress interfaces of the router according to the forwarding VRF table.
