Abstract
Although RFC 4302 and RFC 4303 don't prohibit using Extended Sequence Number (ESN) when the anti-replay function is not enabled, many IPsec implementations require ESN to be used only with anti-replay. Therefore, failing to negotiate the use of ESN when the anti-replay is disabled will cause the sequence numbers to exhaust rapidly in high-traffic-volume scenarios, leading to the frequent rekey of Child SAs. This document defines the REPLAY_PROT_AND_ESN_STATUS Notify Message Status Type Payload in the Internet Key Exchange Protocol Version 2 (IKEv2) to inform the peer of its replay protection status and capability of using ESN without anti-replay when creating the Child SAs, to address the above problem.
