Hi Shawn, Thanks for your comments. See below.

The section goes on to state that the Port-Shutdown message > SHOULD be secured through the Tunnel Channel protocol (which is in draft > state). Was this intended to be a normative reference? That reference is out of date. draft-ietf-trill-channel-tunnel has issued as RFC 7978. That should be updated and I agree that this should be a normative reference. > The section quickly > finishes with a reference to Authentication TLVs as a way to secure E-LICS > FS-LSPs traffic. I'm not a TRILL expert and therefore find it difficult to > distinguish between the usage of Tunnel Channels and Authentication TLVs for > securing Port Shutdown messaging. Could you please clarify? "Channel Tunnel", although left in the draft name for convenience, was basically changed to RBridge Header Extension. This is a way to add a layer of header to RBridge Channel messages (specified in RFC 7178) to secure their content. The Authentication TLV is an IS-IS TLV and including that TLV in an IS-IS PDU can be used to secure the content of the PDU. Some text can be added to clarify this. > General comments: > > None. > > Editorial comments: > > s/the need to "inhibition"/the need for "inhibition"/ > s/forarding/forwarding/ > s/two optimization/two optimizations/ > s/messages are build/messages are built/ Thanks for spotting those. We'll fix them. Thanks, Donald =============================== Donald E.
