Option to define address of router in the RA

[jordipalet]

It must be possible to define what address you want to use in the RA. My understanding is that right now, the RA takes the link-local address automatically created with the Interface ID.

However in many other platforms, is possible to decide if you want to use the Interface ID or something different, for example, I want to use FE80::1.

Right now it seems not possible.

Using list ip6addr 'fe80::1/64', in the given interface, will work for now if you manually configure FE80::1 as the default GW in client machines, but the RA still uses the Interface ID.
