Usage
Information
Dell 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 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 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.
