We've been doing this for years on both Juniper & IOS/IOS-XR devices. =
Must be someone else.
We do run into this whole feature parity thing often. The vendors seem =
to be challenged in this space. I suspect a significant part of it is =
they don't actually *use* IPv6 internally or in their lab. We have been =
operating our network with IPv6 for many years now. I believe in most =
cases our connection to the management plane go IPv6 only as well.
It's been fun to see the few SSH over IPv6 defects and other elements =
arise as time has passed, but those days are over. It's just tiring now =
and no longer amusing. (hey you kids, get off my lawn?).
