The Group ID is intended to be used as a port index or a virtual tunnel index. To simplify configuration, a particular PW Group ID at ingress could be part of a Group ID assigned to the virtual tunnel for transport to the egress router. The Group ID is very useful for sending wildcard label withdrawals or PW wildcard status Notification messages to remote PEs upon physical port failure. Corrected Text -------------- - Group ID An arbitrary 32-bit value that represents a group of PWs that is used to create groups in the PW space. The Group ID is intended to be used as a port index or a virtual tunnel index. To simplify configuration, a particular PW Group ID at ingress could be part of a Group ID assigned to the virtual tunnel for transport to the egress router. The Group ID is very useful for sending wildcard label withdrawals or PW wildcard status Notification messages to remote PEs upon physical port failure or transport tunnel failure. Notes ----- The PW group can be created on basis of the transport tunnel index. So Group Id can be used to send PW wildcard status notification to remote PEs on physical port failure or Transport tunnel failure. --VERIFIER NOTES-- Based on input from the Chair and pals wg members, I have rejected this errata.

Document: draft-ietf-pals-ethernet-cw-05.txt
Reviewer: Harish Sitaraman
Review Date: 23 May 2018
IETF LC End Date: 29 May 2018
Intended Status: Standards Track

Summary:
This document is basically ready for publication, but has nits that should = be
considered prior to publication.

Comments:
This document is well written. The context is specified: RAC has been issui= ng
more Ethernet addresses starting with 0x4 or 0x6 and existing ECMP implemen= tations may
examine the first nibble after the MPLS label stack to determine whether th= e
labeled packet is IP or not. This can cause unreliable inference of the pay= load
type at transit routers that may have been inspecting the first nibble.

For my understanding, it would be useful to know how section 5 relates (or<= br> offers more clarity) to the recommendation that CW MUST be used - the solut= ions
in section 5 are known for better ECMP and applicable regardless of whether= the
packet has the CW. With the statement "However in both cases the situa= tion is
improved compared...based on the five tuple of the IP payload.", is th= e point
that hashing would be "improved" (for some definition) since inco= rrect
identification of payload is corrected but yet we cannot precisely steer th= e
OAM packet along the specific ECMP path that the data packet may have taken= ?

What is the intent behind the final paragraph in section 5 considering it mentions the existing stacking order of labels between PW, LSP and EL/ELI -=
could this paragraph be removed or should it also mention the flow label po= sition
from Fat PW?

Major Issues:
No major issues found.

Minor Issues:
Section 2: RFC2119 has been updated by RFC8174.

Nits:
Section 5: LSP entropy labels specified 'in' [RFC6790]

Check if style consistency for references might be useful:
=C2=A0 Section 4: RFC6391 [RFC6391] vs. [RFC6391] vs. RFC6391 - all are use= d in the document.
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2= =A0Similarly for RFC6790 references.
=C2=A0 Section 4/5: EL - expanded first in section 5, 3rd para "entrop= y label (EL)" but used earliest in section 4.
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2= =A0 =C2=A0 Might be better to expand ELI too.

There are two cases we had to deal with: The main one where a PW without the CW was being deployed, in which case LSR's on the path were doing five tuple based ECMP (and making mistakes). The other case that came to light was LSRs that noting the presence of the PW by noting that the first nibble after the label stack was zero, and then (sometimes) falsely concluding that what followed the label stack was CW, Ethernet Header, IP packet and using the five tuple in the assumed IP packet to do ECMP, sometimes getting it wrong. Thus the point of this section was to explain how to correctly do ECMP on a PW. > With the statement "However in both cases the situation is > improved compared...based on the five tuple of the IP payload.", is the point > that hashing would be "improved" (for some definition) since incorrect > identification of payload is corrected but yet we cannot precisely steer the > OAM packet along the specific ECMP path that the data packet may have taken? An OAM packet does not have the five tuple, so cannot follow the same path as a five tuple packet by definition. The situation is improved if one of the non-five tuple methods are used and the same ECMP hints are included in both data and OAM packets since LSRs would select the same next hop in both cases. > What is the intent behind the final paragraph in section 5 considering it > mentions the existing stacking order of labels between PW, LSP and EL/ELI - > could this paragraph be removed or should it also mention the flow label position > from Fat PW? This text was added as a result of a WG LC comment where a reviewer wanted clarification of the ordering of these LSEs. I am not sure why anyone would want to use both EL and FAT on the same packet. FAT is always after the PW label and thus always BoS. The question the arose where would the EL go if that was used instead. The agreement was reached that since the EL was associated with the LSP, rather than the PW, and there where there is no FAT label the PW label is always BoS, it made sense for the EL to be somewhere in the LSP part of the label stack. However we also decided that it was none of our business specifying where in the label stack it belonged, other than not at the bottom. Hopefully that explanation addresses your concern. I have not changed any of the text. > Major Issues: > No major issues found. > > Minor Issues: > Section 2: RFC2119 has been updated by RFC8174.

This draft is a work item of the Pseudowire And LDP-enabled Services WG of the IETF. Title : Use of Ethernet Control Word RECOMMENDED Authors : Stewart Bryant Andrew G Malis Ignas Bagdonas Filename : draft-ietf-pals-ethernet-cw-06.txt Pages : 9 Date : 2018-05-25 Abstract: The pseudowire (PW) encapsulation of Ethernet, as defined in RFC 4448, specifies that the use of the control word (CW) is optional. In the absence of the CW an Ethernet pseudowire packet can be misidentified as an IP packet by a label switching router (LSR). This in turn may lead to the selection of the wrong equal-cost-multi- path (ECMP) path for the packet, leading in turn to the misordering of packets. This problem has become more serious due to the deployment of equipment with Ethernet MAC addresses that start with 0x4 or 0x6. The use of the Ethernet PW CW addresses this problem. This document recommends the use of the Ethernet pseudowire control word in all but exceptional circumstances. This document updates RFC 4448.
