hostRecvRedirect4RFlag verifies that an entry of Destination Cache updated by a redirect message (ICMP Target != ICMP Destination) is removed by NA w/ RFlag=0.

1. NUT must throw echo-reply whose destination is off-link global to the default router (i.e. R1).
Send RA with RouterLifetime=0 to clear the Default Router List.
