zeroconf and addressing

Sorry to keep bringing this up but I hope it helps get correct information on the page.

For link-local auto-configuration, are routes necessary? These are prefixed by fe80::/80 suffixed with the NIC's MAC address.

For auto-configured, globally routable addresses, net-misc/radvd *should* configure addressing and routing, much like DHCP does in IPv4 (RFC4861).

What about IPv6 over secure wireless? wpa_supplicant requires the interface to be up, but addressing requires wpa_supplicant to be connected (right?). If wpa_supplicant connects after a delay (as is normal), does the interface get its address?

Not exactly related, but there is also IPv6 ULA (RFC4193, FC00::/7).

re: zeroconf and addressing

My understanding is that link-local addresses are non-routeable (local LAN only) and thus don't require any routes to be set.

Yes, we/you can add information about radvd, but it is only used when you are configuring your system to act as a router, at least that it is my understanding.

I don't understand the wpa_supplicant issue, but I haven't used IPV6 over wireless with Funtoo yet.

re: radvd

I see I misunderstood. I assumed that, as consumer IPv6 tech is not widely available, all users would be running a linux router with radvd. It is possible that other ND/router advertisements do not set routes...
