>Agreed. Anyone wanting to do this is not connected with actual operations and should be questioned as to what the operational requirements are. Accepting and sending redirects also opens up dos vectors >to devices when implemented poorly. If you have a problem with ND Redirect being a DOS vector, then you should have raised an issue with RFC 4861. Anyway, RFC 4861 is clearly aware of the DOS vector with Redirect, because RFC 4861 mentions Redirect rate limiting in section 8.2. DOS vector is a very weak reason to shoot down "Redirect functionality MUST be implemented by a router in the Node Req document".
