Configuring gated

Configuring the RIP Protocol

•[secondary] authentication [none[simplemd5] 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 -eand -aconfiguration 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 -eoption 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 -aoption, 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 -eand -aoptions either on the command line or in the configuration file. Configuration file options override the command-line options.
