Abstract: There is provided an apparatus, said apparatus including circuitry for, at a distributed unit of a relay node, determining that an internet protocol, IP, address of the distributed unit of the relay node used for communicating with a centralised unit of a donor node over a first communication path including a first donor distributed unit is to be reused after a change from the first communication path to a second communication path including a second donor distributed unit and providing an indication to the control plane of the centralised unit of the donor node that the IP address is to be reused.
