Abstract: This disclosure describes techniques relating to assigning unique segment identifiers (SIDs) in a segment routing network. In one example, this disclosure describes a method that includes receiving, by a computing system and from a node on a network, a request to allocate a segment identifier for use in a segment routing network; allocating, by the computing system and from a block of addresses, an assigned segment identifier; responding to the request by outputting, by the computing system and over the network to the node, information about the assigned segment identifier; and maintaining the assigned segment identifier.

Abstract: This disclosure describes techniques that include determining, at an egress node in an SRm6 network, how to process a packet that may arrive without a segment routing header and/or a compressed routing header. In one example, this disclosure describes a method that includes receiving, by an egress node of a segment routing network, segment routing advertisements; configuring, by the egress node and based on the segment routing advertisements, information enabling the egress node to recognize encapsulated packets arriving at the egress node without a compressed routing header; receiving, by the egress node, a packet that does not have a compressed routing header; and de-encapsulating, by the egress node and based on the stored information, the packet.

Abstract: An extend ping protocol is described that allow connectivity tests to be performed for individual network interfaces of a target device without requiring network reachability between the testing device and the remote interface whose status is being queried. Moreover, the extend ping protocol supports a plurality of different probe types that allow an administrator to control how identification information within an extended ping echo request is resolved to the unreachable interfaces.

Abstract: This disclosure describes techniques for using Operations, Administration, and Management (OAM) operations when routing packets using micro SIDs in segment routing. For example, a network device comprises one or more processors configured to: receive a packet; determine whether the packet is encapsulated with one or more micro segment identifiers (SIDs); in response to a determination that the packet is not encapsulated with one or more micro SIDs, determine whether the packet has reached a segment routing tunnel endpoint; and in response to a determination that the packet has reached the segment routing tunnel endpoint, initiate Operations, Administration, and Maintenance (OAM).
