Speaking as WG member: Co-Authors,
I see you have a slot at the LSR meeting on Thursday to present the subject draft. I believe this document is misguided. You shouldn't need to advertise protected prefixes. If you are doing Source Address Validation for intra-domain sources, why wouldn't you do it for all of them? What do you do for the intra-domain prefixes that aren't advertised (blindly forward them or summarily discard them)? If you were to only do SAV on certain prefixes, this should be a local decision as opposed to something that is advertised by the sources. Also, you shouldn't need to advertise any reverse metric. At least within an area, you have all the reverse costs in link-sate. Incoming interfaces for asymmetric paths can be readily calculated without any IGP advertisement. Algorithms to accomplish this are described in https://patents.google.com/patent/US11882019B1/en?oq=11882019 The SAVNET WG shouldn't adopt any document requiring IGP advertisement without LSR approval. Thanks, Acee _______________________________________________ Lsr mailing list [email protected] https://www.ietf.org/mailman/listinfo/lsr
