- * XXX also has the problems getting the FIB from curthread which will not

+ * Control interface address fib propagation.
+ * By default, interface address routes are added to the fib of the interface.
+ * Once set to non-zero, adds interface address route to all fibs.
+ * This behaviour is deprecaded and will be removed soon.
