Hi Ken,

Please find the text on Notify message (as agreed during testing at
plugtest)
for IPSP double exchange behavior.

2)  IPSP update

IPSP testing has occurred between different implementations.  Nitin
from Trillium will suggest text on the list to clarify Notify message.

5.5.2 Double exchange:

Hi,

In my opinion, the presented scenario does not follow double-message
approach. How can IPSP-A can send NTFY to IPSP-B, before sending ASPUP and
receiving ASPUP-ACK from it? And also, it this scenario is intended for
double-excahnge scenario (it says 5.5.2. Dopuble exchange) , second
ASPUP/ASPUP-ACK is not optional but mandatory.

    Tolga
