Reviewer: Tina Tsou
Review result: Ready

This is a document that specifies optimized ARP/ND response for RBridge,
when the target's location is known, to avoid ARP/ND query and answer
flooding.

>From security point of view this document is Ready. If it can describe how
to store and transfer the key, it is more complete.

In addition, a flow chart may help the readers to clearly understand the
handling of messages in section 4.

No nit was found.
