ABSTRACT:
A mobile router is configured for attaching to a selected router in a mobile network based on identifying a network topology model of the mobile network from received router advertisement messages that include tree information option fields specifying attributes of the network topology model. The mobile router selects which router advertisement originator to attach to based on correlating the attributes of the router advertisement originators relative to identified priorities, and orders the router advertisement originators within a default router list based on the identified priorities. The mobile router attaches to one of the routers in the ordered default router list having a higher priority, and upon attaching to the router advertisement originator as its attachment router, the mobile router transmits its own corresponding router advertisement message including a corresponding tree option field that specifies the attributes of the mobile router within the network topology model, enabling other routers to selectively connect and/or reconnect within the mobile network based on their respective identified preferences.
