Question for an IPv6 Guru
-
Hi there, I'm hoping that there's someone out there who's familiar enough with IPv6 to answer this question, or someone who can point me in the right direction to finding the answer. Here it goes... Time and time again I read about how hosts don't need to have a default gateway configured statically in IPv6 as they did in IPv4 becuase they will automatically discover the router via Neighbor Discovery Protocol. This is all well and good, except that Linux still supports the manual configuration of a router (route add -inet6 [ipv6_address]). What I don't understand is why this is supported at all. Since IPv6 lacks ARP requests, it seems as though a host would still have to resolve the router via NDP even if a static address is given to it. Can anyone clarify how specifying the L3 address of the gateway without an L2 address along with it is useful to the host? Thanks!

I'm sorry if I offended anyone by posting this question in the General Discussions forum, but I honestly don't know where to turn to and thought that this forum would be the best place to look for a kind soul would could shed some light on this subject, as my readings of RFCs and postings on newsgroups has resulted in fruitless results. Would it be more appropriate to ask for referrals to places that may be able to answer my question?
