Configures the threshold, in kbps, for switching to SPT. On leaf routers, this setting is based on data packets. On the RP, this setting is based on register packets. When infinity option is configured on First Hop Routers or Intermediary Routers, SPT switching is disabled. Traffic forwarding will be performed based on RPT paths only.
| ipv4 | Specifies the IPv4 address family. |
| ipv6 | Specifies the IPv6 address family. |
| infinity | Disables Shortest Path Tree (SPT) switching on Last Hop or Intermediary routers. |
| leaf-threshold | Specifies the rate of traffic per (s,g,v) group in kbps for the last hop. Range is 0 - 4194303. |
| rp_threshold | Specifies an RP threshold. Range is 0 - 4194303. |
The default setting is 0 for both parameters.
For the best performance, use default value of 0.
The following example changes the threshold for switching to SPT:
configure pim spt-threshold 4 16

The infinity option was added in ExtremeXOS 15.7.
