Folks, Ron has requested publication of his experimental ICMP extension document which makes it possible to attach options to IPv4 ICMP messages, mainly the error messages. One background for this work is the use of such extensions in MPLS networks but other uses are possible too.
The discussion on the int-area list was focused on IPv4. But it turns out that at least one vendor has implemented this functionality even for IPv6. I would be interested in hearing feedback on what we should do with these extensions wrt. IPv6. Perhaps we want the spec to say how to do it for IPv6 too or maybe we want to do something completely different. Or it could be that such extensions are inappropriate or unnecessary. Or that we don't care. In any case, I'd rather have a discussion about this now than at a later time when vendors have already decided to do something. We are discussing this on the int-area list. If you have opinions about it it, please post them.
