1. An apparatus comprising
at least one processor; and
at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus to at least perform:
signalling, to a first network function, a first request to be notified of at least one change in first user plane functions associated with a first 5G virtual network comprising a public network and a private network, the public network for use by user equipment of the private network to access the private network, the first 5G virtual network comprising the first user plane functions and at least one first interface interfacing the first user plane functions with the private network;
receiving, from the first network function, a first indication that the at least one change in the first user plane functions has occurred; and
sending, to a router manager of the private network, an update including information concerning a current architecture of the 5G virtual network for causing the router manager of the private network to update at least one virtual private network tunnel of the at least one first interface from the private network to the public network.
