Hi OSPF, ISIS, and SPRING WGs, As part of the Alia’s AD review, she uncovered the fact that the ERO extensions in 6.1 and 6.2 are specified as far as encoding but are not specified as far as usage in any IGP or SPRING document. As document shepherd, my proposal is that they simply be removed since they were incorporated as part of a draft merge and it appears that no one has implemented them (other than parsing). We could also deprecate types (4-8) in the OSPFv2 Extended Prefix LSA Sub-TLV registry to delay usage of these code points for some time (or indefinitely ;^).
Thanks, Acee
