Hello guys, I got strange problem with BGP i share data to Collector but i put to reject some bgp path.... This is how look configuration of BGP session of Collector: protocol bgp Collector { description "Collector"; local as MY-ASN; source address IPv61; neighbor IPV62 as SOMEONE-ASN; multihop; import none; export filter { if bgp_path.first = 64515 then reject; if bgp_path = 64515 then reject; if bgp_path.last = 64515 then reject; include "export.conf"; }; } But: root@pl-bgp:~# birdc6 show route export Collector all 2a0b:e206::/32 BIRD 1.6.3 ready. 2a0b:e206::/32 via 2a06:1287:330e:16::2 on bgp-fr [France 2017-09-18] * (100) [AS21430i] Type: BGP unicast univ BGP.origin: IGP BGP.as_path: MY-ASN 64515 20473 1299 21430 BGP.next_hop: 2a07:XXXX.XXXX.XXXX BGP.local_pref: 100 BGP.community: (64515,44) Like You see in BGP path there is 64515. How i export this to Collector if i put reject on export? What is wrong? I use BIRD 1.6.3. Best Regards Marek Krolikowski
