Claim 0:
1. A method, comprising:
receiving a segment routing packet by a router in a network;
responsive to a router data plane ascertaining during fast path processing by a fast path processing unit based on an Operations, Administration, and Maintenance (OAM) segment identifier (SID) of the segment routing packet that the segment routing packet is to be OAM processed by a different processing unit in the router, communicating the segment routing packet to the different processing unit, with fast path processing being hardware-based packet processing by the fast path processing unit; and
OAM processing of the segment routing packet by the different processing unit;
wherein the segment routing packet is an Internet Protocol version 6 (IPv6) packet including an IPv6 header and a segment routing header, with the IPv6 header including an IPv6 Destination Address; and wherein the IP Destination Address includes the OAM SID;
wherein responsive to the OAM SID identifying timestamp behavior, the fast path processing unit communicating a timestamp of a current time along with the segment routing packet to the different processing unit.
