Tom, Thanks for your comments.
A summary of our offlline discussion to feedback to this list. > The above could all be separate interface types, and 2) and > 3) could each be supplemented by additional capabilities: > - optional radio-to-router control protocol to determine the > unequal neighbor costs or router priorities automatically This is outside of OSPF scope, and already going on. > - overhead reduction techniques such as differential hellos > or partial topology reporting. This is the true-MANET situation and Alvaro is following up you on that. Thanks.
