Reviewer: Barry Leiba Review result: Has Nits I understand why it’s easier to do a single document with a batch update, but I question whether anyone will pay attention to it. Still, until the relevant documents are organically replaced and these changes are actually folded into them, this will serve as a placeholder and reminder of the changes that need to be made. (As a side issue, I wonder if, as we move toward incorporating verified errata reports into the display of RFCs, it might make sense to file these also as errata reports, as this update will not show in such a display.) I have only one substantive comment: — Section 8 — Packet reception and dropping on an interface not configured with the packet AF, e.g., IPv4 is possible because a router that doesn't support this specification can still be included in the SPF calculated path as long as it establishes adjacencies using the Instance ID corresponding to the IPv4 AF. In the conversion away from “black holing”, this sentence became much longer and somewhat convoluted. I urge you to do some further rework, including splitting it into two sentences for clarity. -- last-call mailing list last-call@xxxxxxxx https://www.ietf.org/mailman/listinfo/last-call
