Dear All

I have some clarifications and suggestions.

1. Currently TRILL charter says the following 
  "2) Development, within the TRILL protocol context, of requirements
  and specifications for broadcast/multicast (multi-destination) frame reduction; e.g., ARP/ND (Neighbor Discovery) reduction through use of the TRILL ESADI protocol."

I would like to propose to make this framework document a more generic document that address framework for "broadcast/multicast reduction in TRILL" and make ESADI and Directory assisted as part of that and also explain how they fit in to the overall framework. Otherwise it is kind of odd to have a framework for just one approach and not the other.

2. Based on the TRILL WG web page  this draft has a related IPR. If we are proposing to move this as a framework document to the WG status, it is important to clarify how the IPR applies to solutions coming from the framework. In general sense it may not be a good idea to have a framework document that has IPR restrictions. Because framework documents are  too broad in scope.

We've discussed earlier versions of this document in the WG in the past, and it seems like useful information for a technique that helps with ARP and ND scaling. It does not include any protocol changes or extensions.

The document is intended as an informational document (it says "Intended
status: Standard Track" but that is incorrect) explaining how directories can fit into TRILL.

Note that there is claimed IPR associated with the draft:

Please send comments to the TRILL list before June 27.
