Configuring the RIP Protocol
Chapter 3 53
• [secondary] authentication [none|[simple|md5]
password
]
specifies the type of authentication for RIP Version 2 packets (it is
ignored for Version 1 packets). secondary indicates that the
secondary authentication is defined; otherwise, the primary
authentication is defined. If authentication consisting of only a
password is required, specify simple
password
or
password
(where
password
is a quoted string of 0 – 16 characters). If the required
authentication consists of a key that was created with the MD5
algorithm, specify md5. Default: none. (If you do not specify the
authentication clause, the default is primary authentication of
none and no secondary authentication.
• trustedgateways provides a list of routers that provide valid RIP
routing information; routing packets from other routers are ignored.
Default: all routers on the attached networks.
• sourcegateways specifies routers to which you can send RIP routing
packets. If you specify the nobroadcast clause, routing updates are
sent only to routers listed in the sourcegateways clause.
• traceoptions enables tracing for the RIP protocol. See “Specifying
Tracing Options” on page 92.
Configuration Options
The -e and -a configuration options help increase the RIP convergent
time on the HP-UX operating system. You can set these command-line
options in the /etc/gated.conf file under the RIP protocol statement.
The -e option specifies route_expiry_time, which is the expiration time
used by RIP to determine route aging. The minimum value is 1 second,
and the maximum value is 180 seconds. The default value is 180 seconds.
Using the -a option, you can specify the route_update_time option.
route_update_time is the time in seconds required by the RIP protocol
to send RIP updates to other nodes on the network. The minimum value
is 1 second, and the maximum value is 30 seconds. The default value is
30 seconds.
Alternatively, you can manually change the value in the
/etc/gated.conf file. You can specify the -e and -a options either on
the command line or in the configuration file. Configuration file options
override the command-line options.
