If in contrast,
the FlowSpec rule announced from r1 to r2 are originally from
r1's policy map, it might work (?).

should have to...... :)
I can now confirm it does.

So, as you already suggested,
there is a difference in those rules which are emited originally by freertr
(via policymap/access-list) and those rules which are originally emited by
exabgp.


I will continue investigation and let you know.


And I will also provide the packet trace you requested.
I will work on this now.

Best Regards
David
