Claim 0:
1. A method implemented by a first node in a network, wherein the method comprises:
receiving, from a second node in the network, a packet destined for a third node in the network, wherein the packet is an Internet Protocol version 6 (IPv6) packet;
making a determination that a first path from the second node to the third node is faulty, wherein the first path is based on a first segment identifier;
adding, in response to the determination, a second segment identifier to the packet to obtain a modified packet, wherein the second segment identifier is a Segment Routing over IPv6 (SRv6) segment identifier (SID), wherein the SRv6 SID instructs the modified packet to be forwarded through a new path computed according to a strict shortest path first (SPF) algorithm, and wherein the SRv6 SID corresponds to an SPF flag; and
sending, to the third node through a second path, the modified packet.
