Re: Using IPv6 with prefixes shorter than a /64 on a LAN

The subject says it all... anyone with experience with a setup like
this ?

Unicast addresses must be located in at least a /64 subnet.  No doubt
there are vendors which enforce this (perhaps even in the ASICs), so
deviating from this rule will result in some lock-in.

The Juniper and Cisco equipment I have worked with can handle static LAN
addresses with a mask different from /64 just fine. Same with OSes like
FreeBSD, for instance.

SLAAC obviously won't work.
