IMHO the 3473 exception is too important to bury halfway through the paragraph with a mild sentence beginning with "Note that..." Perhaps the the Path_State_Removed processing merits a new paragraph beginning with: "There is one exception where the receiving node MAY change the state.", or something along that line. (b) It might be good to append the references [RFC3209] [RFC3473] to the first sentence in the Security Considerations, so the readers don't have to guess where those "security considerations are already specified." |

Given the discussion we had about BCPs in Stockholm, why is this a BCP?

I couldn't > actually locate the sections addressed on a cursory inspection. > I think that this would be very helpful to a reader. If for some reason this is difficult, an alternative is to summarize the behaviors that have become common practice in terms of the RFCs that specify the protocols. For example, section 3 talks about the error codes that can be used to report a preempted TE LSP, but it does not tell the reader if this is a subset of the error codes that might seem to apply in this situation based on the protocol specification. |

All checks made, the documents uses the new boiler-plate; there are no errors in the nits. There are a couple of warnings in part this is becasue the documents references each other and the document that is published first will soon have "Outdated references" to the orthers, since you can't published with future references. In part this is because one of the drafts says "Category: Standards Track" rather than "Intended stauts: Standards Track" and the nits tool does not recognize this. I guess that this is rather common and could be fixed by the RFC-ED, since this a filed that is changed anyway. > (1.h) Has the document split its references into normative and > informative?

It does also request a new error sub-code value for the case of Soft Preemption. The IANA section is present in the draft-ietf-mpls-gmpls-lsp-reroute-03.txt: The document request that IANA upon approval of this document shall make assignment in the "Error Codes and Globally-Defined Error Value Sub-Codes" section of the "RSVP Parameters" registry for the parameteres defined in the document. > (1.k) The IESG approval announcement includes a Document > Announcement Write-Up.

Technical summary: draft-ietf-mpls-3209-patherr-03.txt: This ID describes a common practice when a node sends or receives an RSVP Path Error message for a preempted MPLS-TE LSP. This document does not define any new protocol extensions. draft-ietf-mpls-soft-preemption-14.txt: This document specifies MPLS-TE soft preemption through a number of protocol extensions. The goal is to reduce/eliminate traffic disruption on preempted TE LSPs. Earlier MPLS RSVP-TE is defined supporting only immediate TE LSP displacement upon preemption. The draft defines a reroute request notification which more gracefully mitigate the re-route process of preempted TE LSP. This may lead to a sitution of under-provioning while the soft preemption is executed. For this reason, the feature is primarily of interest in MPLS enabled IP networks with Differentiated Services and Traffic Engineering capabilities. draft-ietf-mpls-gmpls-lsp-reroute-03.txt: This document describes how RSVP PathErr Messages may be used to trigger rerouting of MPLS andGMPLS point-to-point TE-LSPs without first removing LSP state or resources. Yhere are a number of cases where such rerouting is beneficial, e.g. soft-preemption and graceful shutdown. This document defines a new reroute-specific error code to allow for future definition of reroute application-specific error values. > Working Group Summary > Was there anything in WG process that is worth noting? For > example, was there controversy about particular points or > were there decisions where the consensus was particularly > rough? The soft/preemeption draft is "old" and been around for along time. There have been several attempts to resolve the issues, and the other two draft turned out to be necessary to cover all issues. There have been two major issues - both sof and hard preemption has ben poorly defined - existing specification in MPLS and GMPLS have not been totally in synch, draft-ietf-mpls-gmpls-lsp-reroute-03.txt resolves this > Document Quality > Are there existing implementations of the protocol?
