Document: draft-ietf-trill-centralized-replication-10.txt Reviewer: Francis Dupont Review Date: 20171209 IETF LC End Date: 20171212 IESG Telechat date: unknown Summary: Ready with Issues Major issues: None Minor issues: C-nickname is used before being defined Nits/editorial comments: - Abstract page 1: please expand the RPF abbrev - Abstract page 1 and 1 page 3: Mutlicast -> Multicast - ToC page 2 and 3 title page 5: Centralized Replication Solution Overview -> Centralized replication solution overview (mainly for consistency) - ToC page 2 and 6 title page 8: a edge group -> an edge group (It seems both are accepted?) - ToC page 2 and 9 title page 12: I have a little concern with the CMT abbrev which BTW is not in the RFC Editor list (https://www.rfc-editor.org/materials/abbrev.expansion.txt) I suggest to add "(RFC 7783)" after CMT - ToC page 3 and 10 title page 13: Network Upgrade Analysis -> Network upgrade analysis (still consistency) - 1 page 3: at the first read it was not obvious that RBv is just the notation for a virtual RBridge. I suggest to do the same than for RBn, i.e., to change the first occurrence from RBv to (RBv). - 1 page 3: my US English spell checker does not accept learnt (it wants learned ???) - 2 page 4: please move from RFC 2119 to its update RFC 8174 - 2 page 4: LAALP -Local -> LAALP - Local - 3 page 5 title: cf ToC comment - 3 page 5: " BUM packet should be..." an example of a lower case "should" which can take benefit of RFC 8174 (vs RFC 2119). Note there are two other "should"s next page and a "may" in 4 (and other lower case keywords). - 3 page 6: C-nickname is used without explanation of what it is (the explanation is in 9 page 12 so far later). Some words and/or a forward reference should solve the issue. - 8 page 11 (last line): nodes/ multiple -> nodes / multiple - 9 page 12 title: cf ToC comment - 9 page 12: CMT -> Coordinated Multicast Trees (CMT) (at the first occurrence, i.e., first line after figure 2) - 9 page 12: the definition of C-nickname is here. BTW you use both C-flag and C-nickname flag, the second is not very correct from a language point of view but is very clear technically so I shan't object if you keep it. - 10 page 13 title: cf ToC comment - 11 page 13: psudo -> pseudo - Authors' Addresses page 17 (two occurrences): China -> PR China (or you can switch all countries to ISO IS 3166 two letter codes) Regards Francis.Dupont@fdupont.fr
