+.Sh NAME
+.Nm rtquery
+.Nd query routing daemons for their routing tables
+.Sh SYNOPSIS
+.Nm
+.Op Fl np1
+.Op Fl w Ar timeout
+.Op Fl r Ar addr
+.Ar host ...
+.Sh DESCRIPTION
+.Nm Rtquery
+is used to query a network routing daemon,
+.Xr routed 8
+or
+.Xr gated 8 ,
+for its routing table by sending a
+.Em request
+or
+.Em poll
+command.  The routing information in any routing
+.Em response
+packets returned is displayed numerically and symbolically.
+.Pp
+.Em Rtquery
+by default uses the
+.Em request
+command.
+When the
+.Ar -p
+option is specified,
+.Nm rtquery
+uses the
+.Em poll
+command, an
+undocumented extension to the RIP protocol supported by
+.Xr gated 8 .
+When querying gated, the
+.Em poll
+command is preferred over the
+.I 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.  Routed does not answer the Poll command, but
+recognizes Requests coming from rtquery and so answers completely.
+.Pp
+.Em Rtquery
+is also used to turn tracing on or off in
+.Em routed .
+.Pp
+Options supported by
+.Nm rtquery :
+.Bl -tag -width Ds
+.It Fl n
+Normally network and host numbers are displayed both symbolically
+and numerically.
+The
+.Fl n
+option displays only the numeric network and host numbers.
+.It Fl p
+Uses the
+.Em Poll
+command to request full routing information from
+.Xr gated 8 ,
+This is an undocumented extension RIP protocol supported only by
+.Xr gated 8 .
+.It Fl 1
+query using RIP version 1 instead of RIP version 2.
+.It Fl w Ar timeout
+changes the delay for an answer from each host.
+By default, each host is given 15 seconds to respond.
+.It Fl r Ar addr
+ask about the route to destination
+.Em addr .
+.It Fl t Ar op
+change tracing, where
+.Em op
+is one of the following.
+Requests from processes not running with UID 0 or on distant networks
+are generally ignored by the daemon except for a message in the system log.
+.El
+.Bl -tag -width Ds -offset indent-two
+.It Em on=tracefile
+turn tracing on into the specified file.  That file must usually
+have been specified when the daemon was started or be the same
+as a fixed name, often
+.Pa /etc/routed.trace .
+.It Em more
+increases the debugging level.
+.It Em off
+turns off tracing.
+.It Em dump
+dumps the daemon's routing table to the current tracefile.
