Usage Information

Dell EMC Networking OS supports standard access lists for the SSM range. You cannot use extended ACLs for configuring the SSM range. If you configure an extended ACL and then used in the ip pim ssm-range {access list name} configuration, an error is reported.

However, if you configure ip pim ssm-range {access list name} first and then you configure the ACL as an Extended ACL, an error is not reported and the ACL is not applied to the SSM range.

Dell EMC Networking OS-recommended best-practices are to configure the standard ACL, and then apply the ACL to the SSM range. After the SSM range is applied, the changes are applied internally without requiring clearing of the tree information base (TIB).

When the ACL rules change, the ACL and protocol-independent multicast (PIM) modules apply the new rules automatically.

When you configure the SSM range, Dell EMC Networking OS supports SSM for configured group range as well as the default SSM range.

When you remove the SSM ACL, PIM SSM is supported for the default SSM range only.
