IDR WG Last Calls and adoptions for the following IDR BGP LS related drafts have hit a road block due two issues: concerns regarding message size and error handling problems: WG LCs . draft-ietf-bgp-ls-segement-routing-rld-03.txt, . draft-ietf-bgp-ls-segement-routing-md-02.txt , . draft-ietf-bgp-idr-te-lsp-distribution-09.txt Adoptions: . draft-ketant-idr-bgp-ls-app-specific-attr, . draft-wu-idr-bgp-segement-allocation-ext . draft-li-bgp-ls-sbfd-extensions . draft-ketant-idr-bgp-ls-flex-alo One solution to the message size issue is to simply standardize draft-ietf-bgp-extended-message-27.txt with the level of implementation experience we have at this point. A WG call for this will start today. Since the error handling issues are common to BGP-LS, Sue asked Alvaro to discuss the error handling during December on IDR, SPRING, and LSVR. On 12/19/2018 Alvaro Retana sent a query regarding error handling for BGP-LS as he reviewed draft-ietf-idr-bgp-ls-segment-routing-ext. AFAWK (As far as we know), there was no clear agreement on the problem or potential solutions. The chairs will be discussing further work on the error handling issues with other chairs of groups impacted (BESS, SPRING, LSVR). . In order to not slow down any BGP-LS or segment routing drafts, the IDR WG will "provisionally" complete WG LC and adoptions. . For WG LC, provisional means that we will complete all other facets of the WG LC process and get an early AD review. After IDR at IETF 104, the chairs will suggest changes across all drafts. . For WG Adoption, provisional means we will adopt the drafts with the caveat that the error handling may need to change. This message is a WG call for comments on this approach to get us past the BGP-LS draft road block. Sue Hares and John Scudder
