The rtquery utility is used to query a RIP network routing daemon, such as routed(8), for its routing table by sending a request or poll command. The routing information in any routing response packets returned is displayed numerically and symbolically.
The rtquery utility by default uses the request command. When the -p option is specified, rtquery uses the poll command, an undocumented extension to the RIP protocol supported by the commercial gated routing product. When querying gated, the poll command is preferred over the request command because the response is not subject to Split Horizon and/or Poisoned Reverse, and because some versions of gated do not answer the request command. The routed(8) utility does not answer the poll command, but recognizes requests coming from rtquery and so answers completely.
The rtquery utility is also used to turn tracing on or off in routed(8).
The following options are available:
