A method and apparatus for preventing a user equipment (UE) from forming of a routing loop in a network. The method includes maintaining a list of one or more home addresses associated with the user equipment (UE), in which each home address has been previously associated with the user equipment (UE) by a corresponding packet data network gateway (PDN GW). In response to a request to update a care-of address in a binding cache entry of a packet data network gateway (PDN GW) in the network, the method further includes comparing an address to be used to update the care-of address with the one or more home addresses in the list. If the address to be used to update the care-of address matches a home address in the list, then the update is rejected.
