--------------------------------------
Type: Editorial
Reported by: Leaf Yeh <[email-masked]>

Section: 2.5

Original Text
-------------
   In order to provide proper
   source address validation, it is critical that the information
   distributed among the different FCFS SAVI devices be coherent.

Corrected Text
--------------
   In order to provide proper
   source address validation, it is critical that the information
   distributed among the different FCFS SAVI devices be not coherent.

Notes
-----
The above revision then complies with the other statements in the same paragraph:

<quote>
In particular, it is important to avoid having the same source address bound to different binding anchors in different FCFS SAVI devices. Should that occur, then it would mean that two hosts are allowed to send packets with the same source address, which is what FCFS SAVI is trying to prevent.  In order to preserve the coherency of the FCFS SAVI bindings distributed among the FCFS SAVI devices within a realm, the Neighbor Discovery (ND) protocol [RFC4861] is used, in particular the Neighbor Solicitation (NS) and Neighbor Advertisement (NA) messages.
