Use the SSM range parameter to extend the default SSM range of 232/8. By modifying the SSM range, you can configure existing applications without having to change their group configurations.
The other global parameters in this dialog box enable the IGMPv3 dynamic learning feature and set the administrative state for all the entries in the SSM channel table.
Attention If you change the RangeGroup configuration, the switch reinitializes PIM and temporarily stops all PIM traffic. For those multicast groups out of SSM range (for example, under PIM-SM behavior), this procedure also causes a rendezvous point (RP) relearn delay of up to 60 seconds. This delay can be longer if the bootstrap router (BSR) is local. |
