Protocol Independent Multicasting - Sparse Mode (PIM-SM) Protocol Help

PIM-SM Global Configuration

Configurable Data

• PIMSM Admin Mode - Select enable or disable from the pulldown menu to set the administrative status of PIM-SM in the router. You must enable IGMP before enabling PIM-SM. The default is disable.

• Join/Prune Interval - Enter the interval between the transmission of PIM-SM Join/Prune messages. The valid values are from (10 to 3600 secs). The default value is 60.

• Data Threshold Rate - Enter the minimum source data rate in K bits/second above which the last-hop router will switch to a source-specific shortest path tree. The valid values are from (0 to 2000 K bits/sec) . The default value is 50.

• Register Threshold Rate - Enter the minimum source data rate in K bits/second above which the Rendezvous Point router will switch to a source-specific shortest path tree. The valid values are from (0 to 2000 K bits/sec) . The default value is 50.

Command Buttons

• Submit - Send the updated configuration to the router. Configuration changes take effect immediately. These changes will not be retained across a power cycle unless a save is performed.

• Join/Prune Interval - The interval between the transmission of PIM-SM Join/Prune messages.

• Data Threshold Rate - The minimum source data rate in K bits/second above which the last-hop router will switch to a source-specific shortest path tree.

PIM-SM Interface Configuration

Selection Criteria

• Slot/Port - Select the slot and port for which data is to be displayed or configured. Slot 0 is the base unit.

Configurable Data

• Mode - Select enable or disable from the pulldown menu to set the administrative status of PIM-SM in the router. The default is disable.

• Hello Interval - Enter the time in seconds between the transmission of which PIM Hello messages on this interface. The valid values are from (10 to 3600 secs) . The default value is 30.

• CBSR Preference - Enter the preference value for the local interface as a candidate bootstrap router. The value of -1 is used to indicate that the local interface is not a candidate BSR interface. The valid values are from (-1 to 255) The default value is 0.

• CBSR Hash Mask Length - Enter the CBSR hash mask length to be advertised in bootstrap messages if this interface is elected as the bootstrap router. This hash mask length will be used in the hash algorithm for selecting the RP for a particular group. The valid values are from (0 to 32). The default value is 30.

• CRP Preference - Enter the preference value for the local interface as a candidate bootstrap router. The value of -1 is used to indicate that the local interface is not a candidate BSR interface. The valid values are from (-1 to 255). The default value is 0.

Command Buttons

• Submit - Send the updated configuration to the router. Configuration changes take effect immediately. These changes will not be retained across a power cycle unless a save is performed.
