There was a discussion on these drafts some time back and the consensus was that the drafts would not be changed and we would reuse the existing type code for additional authentication types. If there are no further comments then should these be taken up as a new items? > > Presentation Lou Berger: berger-ospf-rfc2370bis followon to ietf66 - opaque > LSA across areas - problem w/validation - so instead rev'd 2370 .. > > Acee wanted MAY or Should added > Acee: when we add new info to TE LSAs - scalability issues - > give priority to base ospf LSA over the opaque LSAs. > Lou: We should take to list whether MAY or SHOULD should be in > the final text. SHOULD sounds too strong to me. This is an implementation specific issue and not all implementations may be able to prioritize OSPF pkts. In view of this, a MAY should be sufficient as a recommendation from the WG. Lets not word it any stronger than this. > > Acee: Will validate on list that this is to become a WG document.
