I don't know what is "!", perhaps "unreachable". This seems (for the moment) quite normal : you're moving, so the metric changes (it will increase at some point), and at some point, you will be out of feasible routes. Babel then must consider that the node has failed, and set the route as unreachable to avoid some routing loops. It is well explained in the 2.8 paragraph of the RFC :
	http://www.ietf.org/rfc/rfc6126.txt

> These negative routes remain persistent until i restart babeld and sometimes until i reboot the host.

It should. How many time before reboot ?

> Is there any way to fix this?

What version (or commit) are you using ? Which OS ?

> Also, is it possible to redistribute routes added with proto kernel or boot?

Yes. Proto boot is avoided by default, so you must add a configuration line, as :
	redistribute proto 3 allow

Best regards,
