+ * Define parameters for NFD RIB commands
+ *
+ * When validating an NFD RIB command, NLSR is only concerned with the
+ * name in the command. However, a request is rejected if it has
+ * unsolicited fields, so the origin, which is set by NFD's RIB, must
+ * be considered optional. We consider these to be secure because they
+ * are currently only received over the localhost prefix. These serve
+ * to support NFD RIB to NLSR route readvertising.
