Re: [Manet-dt] IANA Port & Multicast Addresses

["Pedro M. Ruiz" <[e-mail]>]

Hi,

The draft looks fine to me. I just have a more general question 
regarding the need of the "All-MANET-Nodes" multicast group.

What is the difference between "All-MANET-Nodes" and "All-hosts 
(224.0.0.1)" in terms of which nodes receive those messages?

Wouldn't it be fine to use "All-MANET-Routers" for MANET nodes 
participating in the routing, and "All-hosts" (224.0.0.1) instead of  
"all MANET nodes"?

Regards,

--Pedro
