I performed an OPS-DIR review of draft-ietf-trill-irb-13.txt. Summary: the technical specification seems ready to be published but management considerations are not mentioned. I found the document to be a confusing read, likely because it is not easy to explain the forwarding behavior but I expect that the document is clear enough to implement from. What I did not find was any discussion of management - maybe that is covered in the MIB or OAM documents listed in the TRILL charter. If so, it might be good to reference the right documents. If not, then it would be good to have some suggestions about what to instrument for management. Scott
