Hello, I'm trying to use logical operators like OR and AND on bgpmask filter, but I'm not able, Can you please check if the syntax ir wrong or if is possible to do what I expect to do? The data from output is sanitized. Doesn't work: bird> show route where bgp_path ~ [= 65000 65000 (65002||65001) * =] bird> show route where bgp_path ~ [= 28263 28263 (65002&&65001) * =] The NLRI for the aspath/network exist: bird> show route where bgp_path ~ [= 65000 65000 65001 * =] 203.0.113.0/24 via 192.0.2.2 on em2 [bgp_65001 2018-08-24 from 127.0.0.15] * (100/0) [AS65001i] bird> show route where bgp_path ~ [= 65000 65000 65002 * =] 198.51.100.0/24 via 192.0.2.3 on em2 [bgp_65002 2018-08-22 from 127.0.0.15] * (100/0) [AS65002i] Thanks in advance.
