Claim 14:
15. An apparatus implemented at a first network function (NF), comprising:
a processor; and
a memory coupled to the processor, said memory containing instructions executable by said processor, whereby said apparatus is configured to:
detect that a path between the first NF and a second NF is failed or the second NF is failed, wherein the second NF maintains one or more data network connections or sessions established between one or more user equipments (UEs) and one or more data networks;
select an available second NF for the at least one of the one or more data network connections or sessions;
send at least one address or address range of at least one UE corresponding to the at least one of the one or more data network connections or sessions and a respective priority metric of the at least one address or address range to the available second NE;
the respective priority metric being associated with a valid time, and responsive to the valid time expiring, applying a predefined priority metric to the

at least one address or address range, the respective priority metric having a higher priority than a priority of the predefined priority metric, the higher priority indicating a shorter path toward the at least one address or address range.
