-.Os
-.Sh NAME
-.Nm rip6query
-.Nd RIPng debugging tool
-.\"
-.Sh SYNOPSIS
-.Nm
-.Op Fl I Ar interface
-.Op Fl w Ar time
-.Ar destination
-.\"
-.Sh DESCRIPTION
-.Nm
-requests remote RIPng daemon on
-.Ar destination
-to dump RIPng routing information.
-.Fl I
-lets you specify outgoing
-.Ar interface
-for the query packet,
-and is useful when link-local address is specified for
-.Ar destination .
-.Fl w
-specifies the time in seconds to wait for the initial
-response from a gateway.
-The default value is 5 seconds.
-.\"
-.Sh SEE ALSO
-.Xr route6d 8
-.\"
-.Sh HISTORY
-The
-.Nm
-command first appeared in WIDE Hydrangea IPv6 protocol stack kit.
