Abstract
Various techniques can be used to advertise adjacency segment identifiers (IDs) within a segment routing (SR) network. For example, a method, performed by a first node, can involve identifying an adjacency segment between a first node and a second node; assigning an identifier to the adjacency segment; and sending an Intermediate-System-to-Intermediate-System (IS-IS) hello (IIH) message to another node. The adjacency advertisement includes the identifier. If the adjacency segment is part of a LAN, the IIH message can be sent to a designated node that aggregates adjacency segment ID advertisements for the other nodes on the LAN.
