The 7210 SAS devices support route policies to allow users to enable IGMP group membership report filtering. IGMP group membership report filtering allows the user to configure rules which can be used to restrict the IGMP groups that subscribers/hosts can enroll to. This is achieved by using route policies that specify the set of hosts whose group membership reports are to be accepted (and further processed appropriately by the system) or rejected.
There are no default route policies. Each policy must be created explicitly. Policy parameters are modifiable.
