The import command provides a mechanism to control the (*,G) and (S,G) state that gets created on a router. Import policies are defined in the config>router>policy-options context.
In the import policy, if an action is not specified in the entry then the default-action takes precedence. If no entry matches then the default-action also takes precedence. If no default-action is specified, then the default default-action is executed.
Use the following commands to configure PIM parameters:
config>router# pim
— import {join-policy | register-policy} [policy-name [.. policy-name]
The following example displays the command usage to apply the policy statement which does not allow join messages for group 229.50.50.208/32 and source 192.168.0.0/16 but allows join messages for 192.168.0.0/16, 229.50.50.208 (see the ‟Configuring Route Policy Components” section of the 7450 ESS, 7750 SR, 7950 XRS, and VSR Unicast Routing Protocols Guide).
config>router# pim
— config>router>pim# import join-policy "foo"
— config>router>pim# no shutdown
The following example displays the PIM configuration:
