Uma - We are indeed defining conflict resolution across all the SID advertisements regardless of source (protocol or SRMS) - as the sections you have quoted clearly state.
Why? Because we need consistent use of SIDs in the forwarding plane. From forwarding perspective it matters not whether the SID was advertised by protocol instance #1 or #2 or by an SRMS. What matters is that the SID I use to determine what label I install in my forwarding plane is the same SID that my neighbors will use. Otherwise forwarding will be broken.

As I indicated during meeting - I am not sure why we have to club verification of SIDs advertised through regular protocol reachability prefixes and the ranges advertised through 'Mapping Server' (SRMS). I didn't see any compelling reason to do this. SIDs advertised through reachability prefixes doesn't have ranges unlike SRMS advertisements. As SRMS advertisements are primarily for nodes which are not SR capable and I feel we should not mix this with nodes which are SR capable. This isolation helps restricting the resolution work primarily for multiple SRMS entries advertised through one node or multiple nodes. SRMS advertisements are indeed little bit unique in that you are advertising "configuration" on behalf of node X from node Y with ranges (both prefix ranges and SID ranges). 2. Regarding the scope of conflict resolution: Section 1 " The problem to be addressed is protocol independent i.e., segment related advertisements may be originated by multiple nodes using different protocols and yet the conflict resolution MUST be the same on all nodes regardless of the protocol used to transport the advertisements." Section 3.2.8 " o In cases where multiple routing protocols are in use mapping entries advertised by all routing protocols MUST be included." This sounds like we are seeking to resolve conflicting entries outside and across the protocols? Each IGP has separate mechanism for advertising mapping entry and I this is not clear with the current version of the draft how we can cross verify SID/Prefix conflict across the protocol. Can you clarify this? -- Uma C. -----Original Message----- From: spring [mailto:[email protected]] On Behalf Of [email protected]<mailto:[email protected]> Sent: Thursday, April 14, 2016 12:55 AM To: [email protected]<mailto:[email protected]> Subject: Re: [spring] draft-ginsberg-spring-conflict-resolution - WG adoption call > From: [email protected]<mailto:[email protected]> > Sent: > Thursday, April 14, 2016 9:51 > AM > > Dear WG, > > As we discussed at our meeting last week, working group adoption has > been requested for draft-ginsberg-spring-conflict-resolution. > Please reply to the list with your comments, including although not > limited to whether or not you support adoption.
