Description
This field is to be configured for the last hop router in the RP tree. 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. The user may enter a value
between 0-65535 packets per second. 0 will denote that the last hop router will immediately
enter the SPT once a multicast packet has been received. An entry of infinity will disable the
last hop router from entering the SPT. The default setting is 0.
This field is to be configured for the RP of the distribution tree. 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. The user may enter a value between 0-65535
packets per second. 0 will denote that the RP will immediately enter the SPT once a register
packet has been received. An entry of infinity will disable the RP from entering an SPT. The
default setting is 0.
This command is used to set a time to send a probe message from the DR to the RP before
the Register Suppression time expires. If a Register Stop message is received by the DR, the
Register Suppression Time will be restarted. If no Register Stop message is received within
the probe time, Register Packets will be resent to the RP. The user may configure a time
between 1-127 seconds with a default setting of 5 seconds.
This field is to be configured for the first hop router from the source. After this router sends
out a Register message to the RP, and the RP replies with a Register stop message, it will
wait for the time configured here to send out another register message to the RP. The user
may set a time between 3-255 with a default setting of 60 seconds.
NOTE: The Probe time value must be less than half of the Register
Suppression Time value. If not, the administrator will be presented with an
error message after clicking Apply.
