Even if you have just two routers (and no upstream/downstream issue) you will
see redirect traffic. I don't see this as being a problem (one redirect
per IP destination the host ever sends to isn't a big deal - note that
redirect routes don't need to be timed out in IPv6 since NUD protects
against stale information).
