Hi everyone, I'm presently investigating BIRD as a (much appreciated!) replacement for Quagga and running in to some behaviour that isn't clear from reading the documentation. I'm looking at ways to consistently template BGP communities received from / sent to peers across multiple routers, and have attempted this: define test_international = (test_asn, 90); define test_national = (test_asn, 100); define test_ix = (test_asn, 200); define test_bilat = (test_asn, 300); define test_customer = (test_asn, 400); define test_infrastructure = (test_asn, 500); define test_send_to_transit = [test_blackhole]; define test_send_to_ix = []; define test_send_to_customer = [ test_international, test_national, test_ix, test_bilat, test_customer, test_infrastructure ]; With a view to later making a call to 'filter' in the BGP export filter facing the test customer: bgp_community.filter(test_send_to_customer); However loading this configuration in BIRD produces an error: bird> configure Reading configuration from /etc/bird/bird.conf /etc/bird/template/common.conf, line 84: Number expected Line 84 being the line shown above "define test_send_to_transit = [test_blackhole];". This suggests to me that one cannot define a constant including another existing constant in this manner? If so, is the best approach instead to define constants for individual communities and use re-usable 'functions' to group them logically? Suggestions heartily appreciated :) -- Michael
