Abstract
A method implemented by a first node in a segment routing (SR) network domain includes receiving, from a second node of another network domain, a packet that is to pass through the SR network domain in accordance with segment identifiers (SIDs). The method also includes obtaining compressed SIDs corresponding to some of the SIDs. The method includes generating, by the first node, a segment routing header (SRH) having a list of segments and a segment left (SL) field. The method finally includes adding the SRH to the packet, and forwarding the packet with the SRH to a third node in the SR network domain.
