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 :)
