Abstract
A method and system are disclosed for distributing load in a network. A set of routers are configured for providing IP gateway services to a set of hosts where each router in the set of routers all back up all the other routers in the same set. Each router in the set utilizes identical load distribution policies, load distribution properties and load distribution arrangement. A Load Distribution Function (LDF) master router is determined for the set of routers, wherein each one of the set of routers is a backup for the LDF master router. Every router in the set of routers utilize the same algorithm to compute load distribution and the LDF master router provides balancing information to all the other routers by including that information in VRRP advertisement messages to all the routers.
