I think we're protected (at least) as the standards says.
eg.
 - off-link attacks
 - redirect from non-router for the destination
etc.

I'm not sure if we have other things we can do against this issue.

I think other on-link issues (including "forging" issues) 
will be solved by SEND (SEcuring Neighbor Discovery).
