This document is the product of the IPNG Working Group. The IESG contact persons are Erik Nordmark and Thomas Narten. Technical Summary This document describes a new IPv6 Hop-by-Hop Option type that alerts transit routers to more closely examine the contents of an IP datagram. This option is useful for situations where a datagram addressed to a particular destination contains information that may require special processing by routers along the path. For example, a Router Alert option is included in Multicast Listener Discovery (MLD) packets containing Listener Reports, which are sent to multicast groups but must also be processed by neighboring routers. Working Group Summary This document has traveled a long and tortuous path. At one point, attempts were made to reconcile the differing semantics of the IPv4 and IPv6 Router Alert options. Those attempts were ultimately unsuccessful, as there were compelling reasons for the v6 semantics and the but they were not compelling enough to change the v4 version of the option, which has been deployed. There was support in the WG for the current version of the option and no issues were raised during the last call. Protocol Quality This document has been reviewed for the IESG by Thomas Narten and Erik Nordmark. There are multiple implementations of the option. -------------------------------------------------------------------- IETF IPng Working Group Mailing List IPng Home Page: http://playground.sun.com/ipng FTP archive: ftp://playground.sun.com/pub/ipng Direct all administrative requests to majordomo@sunroof.eng.sun.com --------------------------------------------------------------------
