    Hi all.

    I am having troubles understanding and implementing an IPv6 network

    either there is something wrong with my understanding, or there is something
    wrong with my implementation/brain...

    here is my understanding of what is IPv6 under freebsd.

    in /etc/rc.conf
    ipv6_enabled="yes" turns IPv6 on.

    on boot, looks for a router to get info on IP address (address discovery)

    if no router, fe80:: address created.

    if router that speaks ipv6,
    either globally unicast or site local (fec0::) addresses created.

    because I am in the early stages of messing with this, and also because I want
    to mess with the addresses etc., I am trying to set up 3 networks using site
    local addresses. I am manually assigning fec0::299/64, fec0::172/64 and
    fec0::10/64 networks on the appropriate interface using

    ifconfig vr0 inet6 fec0:0:0:10::/64 anycast
    ifconfig vr0 inet6 fec0:0:0:10::/64 eui64

    questions I have are...

    why can't I ping6 between fe80:: addresses on the network?

    why can't I get static routes to work for the fec0:: addresses (or perhaps a
    better Q would be _how_ do I set up such routes?)

    this is not a link layer or physical layer problem because the ipv4 stuff
    works just fine...

    btw, fec0::10/64 and fec0::172/64 are via wifi and an AP.
