I have two independent ISPs.
Both have a dual stack IPv4 and IPv6.
In IPv4 it is easy to setup failover, redundancy or even loadbalancing.
Just use the Miktrotik as nat router and it works like a charm, with lots of tutorials out there.
But for IPv6...
Because there is no such thing like nat in IPv6, i have no idea how it even might work to have the simplest case - an automatic failover - between two ISPs.
Any hint on how to do this or where to find helpful ressources to read about this?'
Closest tipp I found: Use Linux were NATv6 is availible and do it the old way in software routing. But this is not an option to use on mikrotik.
Any hint helps.
