Is there a way to export (extract) routes from BIRD as a list of
prefixes in text format, to a text file or pipe?

Hi Victor,

You can run bird tool with the -x option to list accepted routes, one per line.
This can be combined with other options such as -a to limit to a specific peer.

Download and more info from here:

Hope this helps.
