Zusammenfassung:	There is provided a method performed by a first donor distributed unit (DU) for routing traffic to a second donor DU in an Integrated Access Backhaul (IAB) network. The method may comprise: receiving an uplink (UL) packet, destined to the second donor DU, from an IAB node, which has a communication path to the second donor DU that is unavailable; appending a header pertaining to a tunnel to the UL packet; and sending the UL packet through the tunnel to the second donor DU, the tunnel being established between the first donor DU and the second donor DU.
