Abstract
A controller determines a first path across a first segment routing (SR) domain and a second SR domain to a destination in the second SR domain, where the first SR domain uses a first SR protocol and the second SR domain uses a second SR protocol. The controller determines SR instructions that enable the interworking of the first SR domain and the second SR domain when data is routed across the first path to the destination. The controller sends, prior to the data being routed over the first path, the SR instructions to at least one of a first router in the first SR domain, a second router in the second SR domain, or a third router in the first SR domain to enable the interworking of the first and the second SR domains for segment routing the data across the first path.
