configure pim spt-threshold

configure pim {ipv4 | ipv6} spt_threshold [infinity | leaf_threshold] {rp_threshold}


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.

Syntax Description

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.

Usage Guidelines

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
