Hi, We use special command (see below) to view information regarding prefixes containing particular BGP communities. When such commands applied, we noticed in logs ---- Aug 27 11:50:17 ekt-rsm1 bird: Filter <NULL> did not return accept nor reject. Make up your mind Aug 27 11:50:17 ekt-rsm1 last message repeated 2690 times ---- Could you explain why? Is there any way to avoid such messages and stay at current logging level? Aug 27 11:50:17 ekt-rsm1 bird: CLI connect Aug 27 11:50:17 ekt-rsm1 bird: CLI: show route all filter {if (0,48642) ~ bgp_community then accept;} table master Aug 27 11:50:17 ekt-rsm1 bird: Filter <NULL> did not return accept nor reject. Make up your mind Aug 27 11:50:17 ekt-rsm1 last message repeated 2690 times Aug 27 11:50:17 ekt-rsm1 bird: CLI connection closed -- Best regards, Mikhail A. Grishin <m.grishin@msk-ix.ru>
