Dear all, I want to inject information into syslog when certain magic prefixes are announced or withdrawn. So far I have this snippet of configuration, but I'd also like to print the BGP AGGREGATOR ip address, and the AGGREGATOR AS number. How can I do this? filter collector_in { if (net ~ [ 84.205.64.0/24, 84.205.65.0/24 ]) then { print "MAGIC PREFIX SIGNALLED: " , net, "' from AS", bgp_path.last, " via AS", bgp_path.first, " [", proto, "]"; accept; } else accept; } How can I get BIRD to print something when a prefix is withdrawn? Kind regards, Job
