Hey Naoki, I am also relatively new to bird, however how I would solve the problem is by nesting functions. As far as I can see, you can accept/reject in functions, too - you are not limited to return true/false. Best, Nico amphineko <sukareki@gmail.com> writes:

Hello there,

I'm a newbie to BIRD, using BIRD 1.6.3 and setting up my first router. I have multiple filters which filter different subnets and apply different attribute modifications.

Currently I put my subnet checks in a function which returns true if a subnet matches, and invoke the function in a filter like this:

function is_asxxxx() { if net ~ [114.51.4.0/24] then return true; return false; }

function is_asyyyy() { if net ~ [19.19.81.0/24] then return true; return false; }

filter f_customers { if is_asxxxx() then accept; if is_asyyyy() then { bgp_community.add((114514, 191981)); accept; } reject; }

I'm wondering if I can invoke other filters inside a filter, so the is_asxxx can also used as an filter. I can't find an example to achieve this.

Regards, Naoki Kobayashi
