I am currently investigating whether RouterOS v7 includes support for SrcAS (Source Autonomous System) data, an information commonly available in most routers (enterprise).
This functionality is crucial for conducting an in-depth analysis of traffic origins between Autonomous Systems.
Despite extensive review of available documentation, I have yet to find a method to create an IPv4/IPv6 template capable of exporting this specific information.
Simply because it’s not necessary, since the official MikroTik documentation does not mention SrcAS
In any case, NetFlow modifications can be implemented in production, as they are more realistic and there is no significant impact.
Certainly, it wouldn’t make much sense to experiment with fictitious AS, but it would be more meaningful to use real data.
As you can see from the official documentation, from its structure, there is no implementation of a template that takes into account the SrcAS information.
