Blackhole IPv6

RouterOS Forwarding Protocols
1

I would like to know how to do blackhole over IPv6. Does anyone know how to do it?

I believe that due to an old Linux kernel in RouterOS you cannot set an IPv6 route blackhole. The nearest workaround (which will do the same job well in many situations) is to set a route unreachable.

Or use firewall rules that do action=drop
