Where can I download RouterOS 3.23 and 3.28?

please use v3.30 from the official webpage.

I downloaded 3.30 from the official site 3 good times.. this is the reult:

ERROR: Cannot install mpls-test-3.30 routing-test-3.30 is not installed, but is required

do what the error says, install also the other package

So install routing-test?

The error is pretty obvious, in order to use mpls-test, you must have the routing-test package installed.
