    Better document router requirements for IPv6

    In order for IPv6 to function correctly for instances, a router
    must be created and added to a subnet. Update the documentation
    to better highlight this as it wasn't clear a router was
    required on an isolated subnet such that Router Advertisements
    messages would be sent.
