DES-7200 Configuration Guide Chapter 7 PIM-SMv6
Configuration
7-13
Note
The probe time must be less than half of registration suppression time.
Furthermore, 3* registration suppression time plus registration probe time
should be no more than 65535s or otherwise the system triggers an alarm.
7.2.25 Configure RP KAT Timer
This command configures the hold time of (S, G) state that registration packets
set up on RP.
To configure RP KAT timer, run this command in the global configuration mode.
Command Function
DES-7200(config)# ipv6 pim
rp-register-kat seconds
Configure KAT timer.
Seconds: in the range 1 to 65535
DES-7200(config)# no ipv6 pim
rp-register-kat
Restore the setting to the default
value, namely 3* registration
suppression time plus registration
probe time.
Caution
The timer should be larger than 3* registration suppression time plus
registration probe time on the source DR, or otherwise the RP may time out the
(S, G) state before the source DR sends the registration packet and thus
leading to temporary interruption of multicast packets.
7.2.26 Configure the Join/Prune Message Sending Interval
By default, the Join/Prune message is sent at the interval of 60s.
To configure the Join/Prune message sending interval, run the following
command in the global configuration mode.
Command Function
DES-7200(config)# ipv6 pim jp-timer
interval-seconds
Configure the Join/Prune message
sending interval.
interval-seconds: in the range 1 to
65535s
DES-7200(config)# no ipv6 pim
jp-timer [interval-seconds]
Restore the setting to the default
value, namely 60s.
Note
When you configure the Join/Prune message sending interval, if the sending
interval * 3.5 is larger than 65535s, the system triggers an alarm and the
sending interval is changed to be 65535/3.5 seconds.
7.2.27 Enable the Last Hop Device to Transfer from the Shared Tree to the
Shortest Path Tree
With this command, a PIM join message is triggered and a source tree is
constructed upon the receipt of the first (S, G) message. The keyword group-list
means all the groups in the list transfer to the source tree. The no form of this
command enables the device to transfer to the shared tree and send a prune
message.
