(Resending w/o the ID announce list - please post any replies against this email please) Folks - Authors of https://datatracker.ietf.org/doc/draft-ietf-isis-segment-routing-extensions/ https://datatracker.ietf.org/doc/draft-ietf-ospf-segment-routing-extensions/ https://datatracker.ietf.org/doc/draft-ietf-ospf-ospfv3-segment-routing-extensions/ received private comments that the specification of the use of the V and L bits in prefix/adjacency SID advertisements differed between the three drafts. Although the differences were not conflicting it might have been confusing to readers of the three specifications and suggest (unintentionally) that the three protocols used these bits in different ways. To eliminate any confusion we have updated all three of these drafts. They all now explicitly state which combinations of V and L bits are valid, what each combination means, and require that invalid combinations MUST be discarded on receive. We emphasize that this is not a specification change - but a clarification. We believe all existing implementations are compatible with the revised language.
