This document relies on the security provided by IS-IS, TRILL ESADI protocol and RFC 6325. The authentication mechanism has been used as a counter measurement to bogus messages. With the use of the authentication, there would be no security exposure. This still holds.

RBv is an handy conception to ease the understanding of the solution. From the view of non AAE RBridges, the group of RBridges in the AAE act just like a single RBridge. 
However, it would be concise to remove the concurrent appearance. 

Thanks,
