The present invention provides a method for distributing Internet Protocol Television (IPTV) content over a national IP backbone using GRE tunneling in a point-to-point ring topology. A logical path is defined that connects multiple hub offices, each including at least two routers, in a ring network topology. Generic Routing Encapsulation (GRE) tunnels are used over an existing Internet Protocol (IP) backbone to establish connectivity between adjacent hub offices. A direction for content flow is defined. The direction of flow may be determined by selecting a designated router. The routers of the hub offices selectively join to upstream routers. This direction may be reversed by changing the direction of in which routers join. IPTV content is distributed over the defined path using the GRE tunnels. The necessity of forwarding the content is determined at each hub office.
