I cannot answer this question.

BIRD is one of the few routing engines that performs exceptionally well
with very large prefix filters. Don't be afraid to deploy large prefix
filters when using BIRD! :-)

A tool like https://github.com/snar/bgpq3 uses IRR data to generate
prefix filters for BIRD, XR, IOS, Junos or JSON format. When I generate
a filter with 'bgpq3 -A -b AS-HURRICANE > /opt/as6939.ipv4.conf' it
generates a 2.7 megabyte file which you can include in your main bird
configuration. 

Hope this helps.

Kind regards,

Job

ps. Don't forget the sysctl advise from the bgpq3 manual
