Abstract
Establishing and advertising co-routed bidirectional paths across multiple domains includes determining a path from the router to a BGP peer, in a Segment Routing (SR) network, as a reverse path SR policy; appending a Binding Segment Identifier (BSID) of the reverse path SR policy in a BGP update message; and sending the BGP update message to the BGP peer. This can be used to ensure an Operations, Administration, and Maintenance (OAM) packet is guaranteed to traverse the same forward and reverse path for fault detection thereon.
