Hi, I'm testing BIRD 2 (version 2.0.2) but I am having issue with the new syntax. More specifically, with arrays. This is a snippet of my configuration: protocol direct direct1 { interface "lo"; debug all; ipv4 { import where net ~ 192.168.60.0/24 ; export none; }; } I start bird and this is the logged output: 2018-06-27T15:26:21.123818+02:00 my.bird.router.com bird: direct1 < address 127.0.0.0/8 on interface lo added 2018-06-27T15:31:19.396405+02:00 my.bird.router.com bird: direct1 < address 192.168.60.10/32 on interface lo added 2018-06-27T15:31:19.396527+02:00 my.bird.router.com bird: direct1 > filtered out 192.168.60.10/32 unicast 2018-06-27T15:31:19.396653+02:00 my.bird.router.com bird: direct1 < address 192.168.60.20/32 on interface lo added 2018-06-27T15:31:19.396778+02:00 my.bird.router.com bird: direct1 > filtered out 192.168.60.20/32 unicast 2018-06-27T15:31:19.397165+02:00 my.bird.router.com bird: direct1 < address 192.168.60.21/32 on interface lo added 2018-06-27T15:31:19.397295+02:00 my.bird.router.com bird: direct1 > filtered out 192.168.60.21/32 unicast 2018-06-27T15:31:19.397419+02:00 my.bird.router.com bird: direct1 < address 192.168.60.12/32 on interface lo added 2018-06-27T15:31:19.397541+02:00 my.bird.router.com bird: direct1 > filtered out 192.168.60.12/32 unicast This works as expected. Now, if I try to use even a 1-member array, like this: protocol direct direct1 { interface "lo"; debug all; ipv4 { import where net ~ [ 192.168.60.0/24 ]; export none; }; } the result is that bird filters out my IPs. These are the relevant log lines: 2018-06-27T15:26:21.123818+02:00 my.bird.router.com bird: direct1 < address 127.0.0.0/8 on interface lo added 2018-06-27T15:26:21.123943+02:00 my.bird.router.com bird: direct1 < address 192.168.60.10/32 on interface lo added 2018-06-27T15:26:21.124277+02:00 my.bird.router.com bird: direct1 > added [best] 192.168.60.10/32 unicast 2018-06-27T15:26:21.124406+02:00 my.bird.router.com bird: direct1 < address 192.168.60.20/32 on interface lo added 2018-06-27T15:26:21.124534+02:00 my.bird.router.com bird: direct1 > added [best] 192.168.60.20/32 unicast 2018-06-27T15:26:21.124913+02:00 my.bird.router.com bird: direct1 < address 192.168.60.21/32 on interface lo added 2018-06-27T15:26:21.125041+02:00 my.bird.router.com bird: direct1 > added [best] 192.168.60.21/32 unicast 2018-06-27T15:26:21.125177+02:00 my.bird.router.com bird: direct1 < address 192.168.60.12/32 on interface lo added 2018-06-27T15:26:21.125304+02:00 my.bird.router.com bird: direct1 > added [best] 192.168.60.12/32 unicast "import where net ~" + "array" has always worked fine with BIRD 1.6. Did the syntax change on v2? Is this a bug? Thanks, Carlo
