Summary:Systems and methods for incrementally eliminating Border Gateway Protocol-Labeled Unicast (BGP-LU) in a multi-region network include receiving BGP-LU updates from one or more Area Border Router (ABR) nodes in a multi-region network with the ABR nodes between two areas including a first area utilizing Segment Routing without utilizing BGP-LU and a second area utilizing BGP-LU; and, responsive to a request from a first node in the first area to reach a second node in the second area, providing a Segment Identifier (SID) list to the first node where the SID list is determined based on the Segment Routing in the first area and the BGP-LU updates from the second area.
