Description

Hello,

I cannot assign a same IPv6 Link-local address to 2 different interface. (through Virtual IPs in the web interface)
Let's say I assign fe80::1 to the LAN interface
If I want to assign the same one to the DMZ interface, I get the error "This IP address is being used by another interface or VIP"
If it makes sense in case of a "normal" public/private ip, it is not when this is a IPv6 link-local address. It is not routable anyway. Moreover it is a usual practice to set the same LL to all the interfaces of a specific router, for easiness.

If it could create a problem for some situation I don't think about, we should get maybe a warning message. But certainly not be unallowed to.

KR,
