Sure! r1, r2, and r3 are FRR clients. BGP relationships are successfully formed and BGP routes are exchanged, but no flowspec is seen on the clients. I am currently analyzing packet captures, but still haven’t completely understood where in the packet header the flowspec is/should be. log syslog all; router id 4.4.4.4; protocol device { scan time 10; } flow4 table flowtab4; protocol static flowspec4{ flow4 { import all; export all; }; route flow4 { dst 172.16.0.1/32; }{ bgp_ext_community.add((generic, 0x80060000, 0x0)); }; } template bgp bgp_fs_temp { local as 4; ipv4 { import all; export all; }; flow4 { table flowtab4; import none; export all; }; } protocol bgp r1 from bgp_fs_temp { neighbor 172.16.4.2 as 1; } protocol bgp r2 from bgp_fs_temp { neighbor 172.16.4.6 as 2; } protocol bgp r3 from bgp_fs_temp { neighbor 172.16.4.10 as 3; Thank you!

However, upon successful configuration of BGP relationships and advertising BGP routes, FRR is not able to see any flowspec rules. Is there a way to check to make sure BIRD is actually sending the flowspec rules with the BGP advertisements? Thanks!
