Hi Donald, > - The draft should be clear that when doing the RPFC for a > multi-destination TRILL Data packet ingressed with a virtual RBridge > nickname, the RPFC must assume that the TRILL Data packet might use > any of the trees that any of the RBk might use. Do you mean that RBn ignores the egress nickname in a received multi-destinaion TRILL data packet with a virtual RBridge nickname when it does RPFC for that packet in that case? Or if I am wrong, please give a clearer explanation on that sentence by using an example.

I suggest that after these and the few other comments have been handled, the -01 version be WG Last Called. - Some acronyms need to be spelled out on first use. - I think Figure 1 and Figure 2 are a bit muddled and should be clarified to show separate connections from each RBk to each CEn. It is also not clear to me why "DRB" occurs in the figures and I think it should be dropped. - The draft should be clear that when doing the RPFC for a multi-destination TRILL Data packet ingressed with a virtual RBridge nickname, the RPFC must assume that the TRILL Data packet might use any of the trees that any of the RBk might use. - The could be problems if a virtual RBridge nickname was taken away by a real RBridge somewhere else in the campus that is higher priority to hold a nickname. Perhaps the draft should suggest that virtual RBridge nicknames are usually configured and should be held with maximum priority with with configured or unconfigured priority ranges, as appropriate... - I think it should be possible to use the Affinity Sub-TLV to change the structure of multi-destination distribution trees in places other than at the edge. So they should be valid as long as they do not conflict even if the requested child is a real RBridge. But, of course, the requested child has to be an adjacent RBridge and the draft should say what it would mean if some RBridge lists, as a requested child for some tree, its parent in that tree.
