Abstract
Embodiments include generating an error message based on an error associated with a b packet, adding to the error message an address of a node in a segment routing domain of a network to serve as a destination address of the error message, and adding a new segment routing header to the error message. Embodiments also include rewriting the packet where the rewriting includes replacing a destination address in the packet with a final destination address associated with the packet. Embodiments further include adding the rewritten packet to the error message, and forwarding the error message to the destination address of the error message. In specific embodiments, the rewriting the packet includes removing a segment routing header of the packet. More specific embodiments include deriving the new segment routing header from information in the packet.
