Abstract
A system and method in an IP-based network for defining a specific router for a host to utilize as a default router. The host is configured with a plurality of preferred correlation values, each of which has a different corresponding preference level. Routers send Router Advertisement (RA) messages to the host and include at least one router correlation value and at least one corresponding priority value. The host compares the received router correlation values with its preferred correlation values and identifies the router that sent the router correlation value that matched the preferred correlation value having the highest corresponding preference level. The identified router is selected as the host's default router. If more than one router matches the preferred correlation value having the highest corresponding preference level, the router that sent the highest priority value is selected.
