Usage Information
Dell Networking OS supports standard access lists for the SSM range. You cannot use extended ACLs for
conguring the SSM range. If you congure an extended ACL and then used in the ip pim ssm-range
{access list name} conguration, an error is reported.
However, if you congure ip pim ssm-range {access list name} rst and then you congure
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 congure 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 congure the SSM range, Dell Networking OS supports SSM for congured group range as well
as the default SSM range.
