The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-lsr-ospf-reverse-metric/ -- DISCUSS: -- I hope this is a quick one. A naive reading of Sec 2.2 implies that a router could generate reverse-metric TLVs quite rapidly, triggering a storm of TLVs from a potentially large number of neighbors. Each reverse metric advertisement generates N LSAs, increasing the amplification of any sort of misconfiguration or misbehavior far more than a traditional LSAs that is updated too often. At the very least, this ought to come up in security considerations, but I wonder if applying some sort of rate limit (beyond which neighbors are free to ignore) would be a firmer way of limiting the problem. I'm flexible on the best way forward. -- COMMENT: -- A "don't be stupid" warning in 2.2 certainly wouldn't hurt, either. ___ Lsr mailing list Lsr@ietf.org https://www.ietf.org/mailman/listinfo/lsr

Similarly, I take it that a length value beyond the end of the message ends processing of the PDU, but the PDU as a whole MUST NOT be discarded. ___ Lsr mailing list Lsr@ietf.org https://www.ietf.org/mailman/listinfo/lsr

The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-isis-te-app/ -- COMMENT: -- I know very little about this, but just checking: - I trust that a network that mixes routers that use application attributes, and not, will not lead to long-term routing loops in spite of them not having a common picture of the network? - It is odd that a link that advertises a zero-length flags field means support for RSVP-TE is “ambiguous” (sec 5). What are the implications of this? When is it OK to use a zero-length flags field given this ambiguity? In a standard, can we not decide on a meaning to eliminate the uncertainty? I would appreciate some language here to answer at least the first two questions. - as the TSVart review points out, the length field wastes 3 bits of 7 because the maximum length is 8. You could reserve them or even use them to encode these three legacy applications. Nits: Abstract: In “these link attributes for a given attribute” add a comma after both instances of attribute(s) Sec 4 2)Application. Add a space Sec 5. Missing a period at the end of “existence of link attribute advertisements” ___ Lsr mailing list Lsr@ietf.org https://www.ietf.org/mailman/listinfo/lsr
