ripquery — query RIP gateways
is used to request all routes known by a RIP gateway by sending a RIP
request or POLL command. The routing information in any routing packets
returned is displayed numerically and symbolically.
is intended to be used as a tool for debugging gateways, not for network
management. SNMP is the preferred protocol for network management.
by default uses the RIP POLL command, which is an undocumented extension
to the RIP specification supported by
on SunOS 3.x and later and by
1.4 and later.
The RIP POLL command is preferred over the RIP REQUEST
command because it is not subject to Split Horizon and/or Poisoned
Reverse. See the RIP RFC for more information.
Send the query as a version 1 packet.
Send the query as a version 2 packet (default).
Specifies the authentication password to use for queries. If
specified, an authentication type of SIMPLE will
be used, if
is specified, an authentication type
of MD5 will be used; otherwise the default is an authentication
type of NONE. Authentication fields in incoming packets will be
displayed, but not validated.
Prevents the address of the responding host from being looked up
to determine the symbolic name.
- -N dest[/mask]
Specifies that the query should be for the specified
instead of complete routing table. The specification of the
optional mask implies a version 2 query. Up to 23 requests about
specific destinations may be include in one packet.
Uses the RIP POLL command to request information from the routing
table. This is the default, but is an undocumented extension
supported only by some versions of unOS 3.x and later versions
If there is no response to the RIP POLL
command, the RIP REQUEST command is tried.
responds to a POLL command with all the routes learned via RIP.
Used the RIP REQUEST command to request information from the
gateway's routing table. Unlike the RIP POLL command, all
gateways should support the RIP REQUEST. If there is no response
to the RIP REQUEST command, the RIP POLL command is
responds to a REQUEST command with all the
routes he announces out the specified interface. Due to
limitations in the UDP interface, on systems based on BSD 4.3
Reno or earlier, REQUESTs respond about the interface used to
route packets back to the sender. This can be avoided by running
on the host being queried.

before querying the gateways.
- -w time
Specifies the time in seconds to wait for the initial response
from a gateway. The default value is 5 seconds.
Some versions of Unix do not allow looking up the symbolic name of a
