Hi, I have one issue I want to bring up as a last call comment. I discussed it briefly with Eric and we agreed it is something that needs wider discussion than just a late editorial change. Currently 6378 does not describe the format of PSC TLVs and draft-ietf-mpls-tp-itu introduces one without defining the format tightly. Therefore, this document contains a simple statement of the fields and meanings in a TLV. However, 6378 also does not state how to handle: - a malformed TLV - an unknown TLV type We need to add some simple text to cover this. Options for each of the above are: - ignore the TLV but process the message - report the TLV but ignore the TLV and process the message - ignore the message - report the message but ignore it - reject the message Thanks, Adrian > -----Original Message----- > From: mpls [mailto:mpls-bounces@ietf.org] On Behalf Of The IESG > Sent: 26 March 2014 19:57 > To: IETF-Announce > Cc: mpls@ietf.org > Subject: [mpls] Last Call: <draft-ietf-mpls-psc-updates-03.txt> (Updates to MPLS > Transport Profile Linear Protection) to Proposed Standard > > > The IESG has received a request from the Multiprotocol Label Switching WG > (mpls) to consider the following document: > - 'Updates to MPLS Transport Profile Linear Protection' > <draft-ietf-mpls-psc-updates-03.txt> as Proposed Standard > > The IESG plans to make a decision in the next few weeks, and solicits > final comments on this action.
