Michael, you are asking that the consensus of the WG be reversed. The errata process is not the way to handle this. You have to go through the motions: write a draft, submit it, get consensus...
-----Original Message----- From: ipv6-boun...@ietf.org [mailto:ipv6-boun...@ietf.org] On Behalf Of Michael Sweet Sent: Wednesday, May 22, 2013 11:10 PM To: Brian E Carpenter Cc: br...@innovationslab.net; ipv6@ietf.org; bob.hin...@gmail.com; ted.le...@nominum.com; RFC Errata System Subject: Re: [Technical Errata Reported] RFC6874 (3630) Brian, What you're apparently missing is that the client is using the zoneid to choose a network interface to route packets to that link local address. If the server returns a uri in its response that uses the same link local address but without the client's zoneid, then the client will be unable to use said uri because it won't know which interface to use. Yes the server doesn't care but the client depends on it (for link local anyways). This issue is specifically why we (the Printer Working Group) require IPP Clients to include the zoneid in the HTTP Host header and require IPP Servers to use the Host value in any generated URIs.
