Section 9.1.1 says:
... If the return value indicates the route is ineligible, the route MAY NOT serve as an input to the next phase of route selection; ...
It should say:
... If the return value indicates the route is ineligible, the route MUST NOT serve as an input to the next phase of route selection; ...
Notes:
RFC 2119 does not define special word MAY NOT. Obviously, ineligible route must not be used in route selection.
