    abstract =  {This document defines a new Stub Router flag in the Router Advertisement message to distinguish configuration information sent by stub routers from infrastructure routers. For example, the Stub Router flag allows stub routers to easily identify when an infrastructure router is advertising a usable IPv6 prefix, triggering the stub router to not advertise its own routable prefix.},
