Abstract
A router (e.g., a home agent for an IPv6 mobile router) is configured for determining a destination router (e.g., the IPv6 mobile router) for a received packet based on accessing a routing table having multiple routing entries, each routing entry including a routing key and a routing field that specifies one of a prescribed address specifying the destination router and a computation tag. The computation tag specifies a prescribed function to be executed to calculate a determined address for the destination router (e.g., the home address for the IPv6 mobile router). The router identifies, for each received packet, the matching routing entry based on the corresponding routing key, and in response to detecting the computation tag in the routing field, selectively executes the corresponding function to calculate the determined address for the destination router.
