A new version of I-D, draft-ietf-trill-smart-endnodes-10.txthas been successfully submitted by Fangwei Hu and posted to theIETF repository.Name:        draft-ietf-trill-smart-endnodesRevision:    10Title:        TRILL Smart EndnodesDocument date:    2018-03-01Group:        trillPages:        15URL:            https://www.ietf.org/internet-drafts/draft-ietf-trill-smart-endnodes-10.txtStatus:         https://datatracker.ietf.org/doc/draft-ietf-trill-smart-endnodes/Htmlized:       https://tools.ietf.org/html/draft-ietf-trill-smart-endnodes-10Htmlized:       https://datatracker.ietf.org/doc/html/draft-ietf-trill-smart-endnodes-10Diff:           https://www.ietf.org/rfcdiff?url2=draft-ietf-trill-smart-endnodes-10Abstract:   This draft addresses the problem of the size and freshness of the   endnode learning table in edge RBridges, by allowing endnodes to   volunteer for endnode learning and encapsulation/decapsulation.  Such   an endnode is known as a "Smart Endnode".  Only the attached edge   RBridge can distinguish a "Smart Endnode" from a "normal endnode".   The smart endnode uses the nickname of the attached edge RBridge, so   this solution does not consume extra nicknames.  The solution also   enables Fine Grained Label aware endnodes.

Summary: Ready with issues

Major issues

1) In section 4.3 the bullet describing the F bit does not parse. There are two
instances of "Otherwise" that do not work together.

2) All of section 4.3 is confusing as to what the length of the TLV really is.
Row 3 in the diagram says 2 bytes or 4 bytes, but the number of bits called out
in bullets 4 and 5 below it don't seem to add up to those things. Maybe it would
be better to draw a diagram with F=0 and a separate diagram with F=1

3) I think the security considerations section should call out again what an RB
should do if it gets message that looks like it's from a SE, containing the
right nickname, but the RB hasn't done the right Smart-Hello handshaking with
that SE already. What would keep a lazy implementation (or one driven by
product managers picking and choosing features) from just forwarding a message
from a malicious element that just happened to know the RB's nickname?

Nits

Terminology: The definition of Transit RBridge says it's also named as a
Transit Rbridge?
