Hello John,
Briefly, expanding rings multicast has been shown to offer faster route
discovery in circumstances where neighboring nodes are likely to have
a route to the destination. For TCP, either end might use it and have
a quicker repair for a broken route.
We wrote a paper about it a long time ago. When I get caught up
with the Security Considerations revision, I'll go look for it.
Regards,
Charlie P.

Hi Charlie
So I have to confess that, while reading your Intermediate RREP draft, I didn't really know what Expanding Rings Multicast was so I went and did some reading, ending up in RFC3561.
I can sort of see what you are describing, in that you are effectively pinging an RREQ in the hope of receiving an RREP on a steadily increasing timeout (if I have understood that correctly). Can you elaborate some use cases on when you have found that facility useful please?
Best regards
John
