Abstract
Router advertisements may be used to configure multi-homed Protocol Data Unit (PDU) sessions. A first router advertisement message from a first PDU session anchor and a second router advertisement message from a second PDU session anchor may be decoded. A user equipment (UE) may identify, based on the first and second router advertisement messages, a first preference value associated with destination routes of the first network and a second preference value associated with destination routes of the second data network. The UE may determine a destination data network for a signal by comparing a destination route of the signal to destination routes associated with whichever data network has a greater preference value. The UE may prepare the signal with a prefix based on the destination data network.
