A method, system, and computer-readable media are provided for maintaining optimized communication after a mobile device transitions to a new foreign agent during a communication session. When a mobile device moves to and registers with a new foreign agent within a communication session, the mobile device's home agent multicasts a message to all foreign agents within an optimization cluster informing them of the updated registration. Accordingly, the foreign agents within the optimization cluster can proceed to transmit data packets directly to the new foreign agent servicing the mobile device within the communication session.
