Hi All,

  I am implementing a function that send default route to BGP peer, and I am facing an issue about BGP filter, when I use “show route filter” in birdc, the filter result is correct; when I add this filter to config-file and start bird, the bird will occur coredump issue. Does anyone know the reason?  Appreciated in advance.

1. bird>show route filter {if format(net) = "0.0.0.0/0" then accept;}  //correct result

/* show route filter {if net = "0.0.0.0/0" then accept;}  // incorrect result  */

2. config-file:

              filter filter_bgp1{

                  if format(net) = "0.0.0.0/0" then accept;  // “format(net) = …” , bird coredump ???

                  /* if net = "0.0.0.0/0" then accept;  // “ net= …” ,  not bird coredump*/

            }

          protocol  bgp bgp1 {

             ……

            ipv4 {

                  import all;

                  export filter filter_bgp1;

          };

          ……..

}

Thanks
