Long time ago I tried it out: https://blog.acostasite.com/2013/02/publicar-prefijos-ipv4-sobre-una-sesion.... https://blog.acostasite.com/2013/02/publicando-prefijos-ipv6-sobre-sesiones.... I did not like, difficult troubleshooting in case something goes wrong (however I can understand it's a nice feature to have and in might be useful in some scenarios). But you are right I do not know much about networks doing it, I also would like hear about it. Alejandro, On 7/29/20 1:51 AM, Douglas Fischer wrote:

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. https://www.youtube.com/watch?v=uJOtfiHDCMw
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?
