Should routers send redirects by default?

Yea the stuff that sometimes is done in hw and sometimes in sw and causes varying pain. You may find the discussion interesting to read if you feel redirects are "ok" or tolerable. 

If vendors can't expose their defaults they really should not be enabling these things as it causes trouble. 

I've had problems with both v4 and v6 redirects. Perhaps you have not.
