Configuring a route policy

Use the import route policy to filter routes imported by the local router from its neighbors. If no match is found, the local router does not import any routes.

Use the export route policy to determine which routes are exported from the route table to RIP. By default, RIP does not export learned routes to its neighbors. If no export policy is specified, non-RIP routes are not exported from the routing table manager to RIP.

If multiple policy names are specified, the policies are evaluated in the order they are specified. The first policy that matches is applied. If multiple export commands are issued, the last command entered overrides the previous command. A maximum of five policy names can be specified.

This section only provides brief instructions to configure route policies. For more details, see the Route policy configuration 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-options
  begin
  commit
  abort
  policy-statement name
    description text
    default-action {accept|next-entry|nextpolicy|drop|reject}
    entry entry-id
      description text
      action {accept|next-entry|nextpolicy|drop|reject}
       from
       to

Use the following CLI syntax to enter the edit mode:

CLI syntax

config>router>policy-options
  begin

The following example displays some commands to configure a policy statement. Policy option commands are configured in the config>router context. Use the commit command to save the changes.

Example

config>router>policy-options# begin
policy-options# policy-statement “RIP policy”
policy-options>policy-statement$ description "this is a test RIP policy”
policy-options>policy-statement>default# entry 1
policy-options>policy-statement>entry$ action accept
policy-options>policy-statement>entry# exit
policy-options>policy-statement# default-action reject
policy-options>policy-statement# exit
policy-options# commit
