George, Thanks for your clarification. Assuming you will add clarification to the draft for the issues raised, you can consider these comments closed. -Shahram From: George Swallow [mailto:swallow@cisco.com] Sent: Thursday, April 29, 2010 7:14 AM To: Shahram Davari; Loa Andersson; mpls@ietf.org; mpls-tp@ietf.org; pwe3@ietf.org; ccamp@ietf.org Subject: Re: [mpls] mpls wg last call on draft-ietf-mpls-tp-identifiers-01 Shahram - See inline On 3/11/10 7:27 PM, "Shahram Davari" <davari@broadcom.com> wrote: Hi, Couple of comments: 1) Why the Interface_ID is 32-bit while the Tunnel_ID is 16-bit? Do we need to support more interfaces than tunnels? GS: Planning to change scope of Tunnel_ID. Just needs to be unique in the context of the Session Object as defined in 3209 with source address used as the extended tunnel-id 2) The draft defines the Global_Tunnel_ID as: Src-Global_ID::Src-Node_ID::Src-Tunnel_Num:: Dst-Global_ID::Dst-Node_ID::Dst-Tunnel_Num This seems to define a bidirectional tunnel. Is that the intent? If so please clarify. If not then why Dst-Global_ID::Dst-Node_ID::Dst-Tunnel_Num is needed? GS: The scope is bidirectional. But I suppose it can be applied to unidirectional as well. I still don't understand the requirement for unidirectional - seems to be that bidirectional with 0 data-bandwidth in the reverse direction would do better as you would have a return path for OAM and DCC etc. 3) Is section 5.2 talking about unidirectional LSP or bidirectional LSP? GS: Ditto 4) Section 7.1.2.1 says: Since a MEG pertains to a single MPLS-TP Tunnel, IP compatible MEG_IDs for MPLS-TP Tunnels are simply the corresponding Tunnel_IDs Assuming the Tunnel_ID is a unidirectional ID, then this statement implies that for the reverse direction a different MEG_ID is required. Is that the intent? If so why? GS: Not unidirectional! 5) Why are drafts part of the normative references? Cut and paste error actually! Thanks for pointing it out! 6) Will section 8 (open issues) be removed before publishing? This section implies that the MEP and MIP definition is not yet aligned with framework? GS: Yes Regards, Shahram -----Original Message----- From: mpls-bounces@ietf.org [mailto:mpls-bounces@ietf.org] On Behalf Of Loa Andersson Sent: Thursday, March 11, 2010 3:33 PM To: mpls@ietf.org; mpls-tp@ietf.org; pwe3@ietf.org; ccamp@ietf.org Subject: [mpls] mpls wg last call on draft-ietf-mpls-tp-identifiers-01 All, this is to start an MPLS working group last call on draft-ietf-mpls-tp-identifiers-01 There is a discussion on the OAM model for MS-PWs where we haven't been able to come to conclusion.
