[Manet-dt] Re: Valid routes vs. active routes

I am currently in the process of refining this very area of the spec.

Here is what I'm thinking (and writing into dymo-06-pre)

Current - routing information that is new, good, and should be
maintained for a while

Recently used - the route has been used for forwarding data recently
and should be maintained for a while

Broken - the link to the next hop broke or a RERR was received that
told me this route isn't good any more

I agree that RERR are only issued for recently used routes. I also
think that only Current and Recently Used routes should actually be in
the forwarding table.

What do you think?
