rtadvd advertise a local link adress as default gateway

[Anthie]

IPv6 Default Gateway: fe80::1eaf:f7ff:fe6f:efeb%15
How can I mod it to advertise global address?

It's normal and should work. Previous versions of rtadvd(8) did advertise the global address but at some point this changed. Not sure why.

Internet6:
Destination                       Gateway                       Flags      Netif Expire
default                           fe80::240:f4ff:fe65:85c2%re0  UG          re0

How can I make it to do the right way it used to be?

I'm not 100% sure but I think the RFCs state it's supposed to send the link-local address instead of a global address. Routers must have a link-local address.

If I read this correctly: http://www.macfreek.nl/memory/Non-Local_IPv6_Router_Advertisement

You need to use net/radvd if you want to advertise the global address.

It works fine in present scenario. It's not not necessary to advertise globe addresses.

I googled a lot of sites, and got this:
A link-local address is also based on the interface identifier.
It identifies where the interface is in networks.
Advertising link-local address makes sense.
