RFC 5549 - IPv4 Routes with IPv6 next-hop - Does it really exists?

Wed Jul 29 05:51:41 UTC 2020

Let's just jump all the arguing about lack of IPv4, the need of IPv6, and
etc...

I must confess that I don't know all the RFCs.
I would like it, but I don't!

And today, I reached on https://tools.ietf.org/html/rfc5549

I knew that was possible to transfer v4 routes over v6 BGP sessions, or v6
routes over v4 BGP sessions.
But I got surprised when I saw this youtube vídeo of AMS-IX guys
considering use a v6 only Lan, and doing v6 next-hops to v4 routes.

Well... I guess that idea didn't go to production.

But the questions are:
There is any network that really implements RFC5549?
Can anyone share some information about it?
