The import command provides a mechanism to control the (*,G) and (S,G) state that is created on a router. Import policies are defined in the config>router>policy-options context.
In the import policy, if a policy action is not specified in the entry, the default-action takes precedence. In the same way, if there are no entry matches, the default-action takes precedence. If no default-action is specified, the default default-action is executed.
Use the following syntax to configure PIM parameters.
config>router# pim
import {join-policy|register-policy} [policy-name]
[.. policy-name]
The following example shows 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 Configuring route policy components).
