config pim rp_spt_threshold
Purpose Used to configure the threshold of register packets needed to
enable the Shortest Path Tree (SPT).
Syntax
config pim rp_spt_threshold [<value 0-65535> | infinity]
Description This command will set the threshold of register packets needed to
enable the Shortest Path Tree (SPT). When the amount of register
packets per second reaches the configured threshold, it will trigger
the RP to switch to an SPT, between the RP and the first hop
router. This command is for PIM-SM configurations only.
Parameters <value 0 –65535> - Enter a value between 0 – 65535 to determine
the number of packets per second needed to Switch the path to a
SPT. The default setting is 0. 0 denotes the router will enter the
SPT immediately.
infinity - An entry of infinity will disable the RP from entering an
SPT.
Restrictions Only administrator-level users can use this command.
Usage Example:
To set the SPT threshold:
DGS-3324SRi:4# config pim rp_spt_threshold 1000
Command: config pim rp_spt_threshold 1000
Success.
DGS-3324SRi:4#
config last_hop_spt_threshold
Purpose Used to configure the packet threshold that the last hop router in
the RP tree will use to change its path to a SPT.
Syntax
config last_hop_spt_threshold [<value 0-65535> | infinity]
Description This command will configure the threshold of multicast data packets
needed to change the last hop router’s distribution tree to a SPT.
When the amount of multicast packets per second reaches the
configured threshold, the last hop router will change its distribution
tree to a (Shortest Path Tree) SPT. This command is for PIM-SM
configurations only.
Parameters <value 0 –65535> - Enter a value between 0 – 65535 to determine
the number of packets per second needed to Switch the path to a
SPT. The default setting is 0. 0 denotes that the router will
immediately enter the SPT.
infinity - An entry of infinity will disable the last hop router from
entering an SPT.
Restrictions Only administrator-level users can use this command.
Usage Example:
To configure the last hop router to never enter an SPT
