Hi. I'm setting up Bird (2.0.7) as a BGP FlowSpec controller and it has to send out FS routes to two (FRR-based) neighbors. Actual configuration is defined as below: flow4 table flowtab4; protocol static { flow4 { import all; export all; }; route flow4 { src x.x.y.y/32; dst x.x.z.z/32; } { bgp_ext_community.add( (generic, 0x80060000, 0x0) ); }; } template bgp bgp_fs { local x.x.x.x as ABCDG; capabilities off; flow4 { table flowtab4; import all; export all; }; ipv4 { import all; export all; }; } protocol bgp bgp_svc01 from bgp_fs { neighbor y.y.y.y as ABCDE; } protocol bgp bgp_svc02 from bgp_fs { neighbor z.z.z.z as ABCDF; } The FS is properly assigned to the BGP protocol instances, but flowtab4 table is only UP as a channel for static1 protocol, while for bgp_svc01/02 is not (hence, no FS routes advertised BGP-side): bird> show protocol all static1 Name Proto Table State Since Info static1 Static flowtab4 up 13:02:42.987 Channel flow4 State: UP ================== Table: flowtab4 Preference: 200 Input filter: ACCEPT Output filter: ACCEPT Routes: 1 imported, 0 exported, 1 preferred Route change stats: received rejected filtered ignored accepted Import updates: 1 0 0 0 1 Import withdraws: 0 0 --- 0 0 Export updates: 0 0 0 --- 0 Export withdraws: 0 --- --- --- 0 bird> show protocol all bgp_svc01 Name Proto Table State Since Info bgp_svc01 BGP --- up 13:00:17.256 Established BGP state: Established Neighbor address: y.y.y.y Neighbor AS: ABCDE Local AS: ABCDG Neighbor ID: whateverID Local capabilities Neighbor capabilities Session: external Source address: x.x.x.x Hold timer: 4.820/9 Keepalive timer: 2.054/3 Channel flow4 State: DOWN ==================== Table: flowtab4 Preference: 100 Input filter: ACCEPT Output filter: ACCEPT Channel ipv4 State: UP Table: master4 Preference: 100 Input filter: ACCEPT Output filter: ACCEPT Routes: 13 imported, 2 exported, 13 preferred Route change stats: received rejected filtered ignored accepted [...] BGP Next hop: x.x.x.x Looking forward to get some clarifications. Thank you. Kind regards, Davide Pucci.
