Hi All,

     When I using bird 2.0.2 version ,I have an issue route include “unreachable”, but I think this application is reasonable , anyone can help me ?

Error is reported in codes:

rt_update_hostentry()

{

  ….

      if (a->hostentry)

                {

                  /* Recursive route should not depend on another recursive route */ -------do you know the reason ??

                  log(L_WARN "Next hop address %I resolvable through recursive route for %N",

                      he->addr, n->n.addr);

                  goto done;

                }

   ……

}

bird> show route all
