• RIP is configured in the config>router>rip context. RIP is not enabled by default. Three hierarchical levels are included in RIP configurations:

•
• This section provides information to configure RIP and examples of common configuration tasks. For a router to accept RIP updates, in the config>router>rip context, you must define at least one group and one neighbor. A router will ignore updates received from routers on interfaces not configured for RIP. Configuring other RIP commands and parameters are optional.The RIP configuration commands have three primary configuration levels: rip for global configurations, group group-name for RIP group configurations, and neighbor ip-int-name for RIP neighbor configurations. Within the different levels, the configuration commands are identical. For the repeated commands, the command that is most specific to the neighboring router is in effect; that is, neighbor settings have precedence over group settings which have precedence over RIP global settings.The minimal RIP parameters that need to be configured in the config>router>rip context are:
•
• ALA-A>config>router>rip# info----------------------------------------------group "RIP-ALA-A"neighbor "to-ALA-4"exitexit----------------------------------------------ALA-A>config>router>rip#
3. The following command sequences create a logical IP interface. The logical interface can associate attributes like an IP address, port, Link Aggregation Group (LAG), or the system. For more information about configuring interfaces, refer to the IP Router Configuration Overview chapter.CLI Syntax: config> routerExample: config>router> interface “to-ALA-4”

For more details, refer to the Route Policy Overview chapter.To enter the mode to create or edit route policies, you must enter the begin keyword at the config>router>policy-options prompt. Other editing commands include:
• The commit command saves and enables changes made to route policies during a session.
• The abort command discards changes that have been made to route policies during a session.Use the following CLI syntax to configure a policy to use for the RIP global, group, and neighbor import and export commands.CLI Syntax: config>router>policy-optionspolicy-statement namedescription textentry entry-iddescription textCLI Syntax: config>router> policy-optionsThe following example displays some commands to configure a policy statement.

Minimally, to enable RIP on a router, at least one group and one neighbor must be configured. There are no default groups or neighbors. Each group and neighbor must be explicitly configured.CLI Syntax: config>routermessage-size numbermetric-in metricmetric-out metricpreference numberno shutdownExample: config>router# ripALA-A>config>router>rip# info----------------------------------------------authentication-type simple
