BGP filter

[Arvin Gan]

Hi ,
  Thanks for your response. 
  Do you know the reason " show route filter {if format(net) = "0.0.0.0/0" then accept;}" is running correctly in birdc command ,but cause the coredump in config-file?  

Thanks
Arvin

compare net = 0.0.0.0/0 - the "0.0.0.0/0" is a string literal, the 0.0.0.0/0 is a prefix literal.
