[lwip-devel] [task #13512] check how IPv6 handles the "no address" case for routing

[Simon Goldschmidt]

Follow-up Comment #1, task #13512 (project lwip):

I'm just looking at ip6_route() (in the context of bug #43904 -ip_route() and
ip6_route() must detect linkup status).

The question to me is do we have to differ between link-local and routable
addresses here? I would have thought yes, meaning we should
- check if the netif has a link-local address set if 'dest' is a link-local
address and
- check if the netif has a routable address set if 'dest' is not a link-local
address

Does that make sense in the IPv6 world? Unfortunately, I'm not too used to
IPv6 to answer this myself :-(
