Title: Encrypted ESP Echo Protocol
Authors: Antony Antony
Steffen Klassert
Name: draft-ietf-ipsecme-encrypted-esp-ping-03.txt
Pages: 11
Dates: 2026-05-04
Abstract:
This document defines the Encrypted ESP Echo Function, a mechanism to
assess the reachability of IP Security (IPsec) network paths using
Encapsulating Security Payload (ESP) packets. It detects end-to-end
path status by exchanging only encrypted ESP packets between IPsec
peers. The Encrypted Echo message can either use existing congestion
control payloads from RFC9347 or a new message format defined here,
with an option to specify a preferred return path when there is more
than one pair of IPsec SAs between the same set of IPsec peers.
A peer can announce support using a new IKEv2 Status Notification
ENCRYPTED_PING_SUPPORTED.
