DES-7200 Configuration Guide Chapter 6 PIM-SM
Configuration
6-12
Command Function
DES-7200(config）# ip pim rp-register-kat
seconds
Configure KAT timer.
seconds: in the range of 1 to 65535.
DES-7200(config）# no ip pim
rp-register-kat
Use the default KAT value
6.3.27 Configuring the Interval of Sending the Join/Prune Message
By default, the Join/Prune message is sent at the interval of 60s by default.
Execute this command to modify this interval.
To modify the interval of sending the Join/Prune message, execute the following
commands in the global configuration mode:
Command Function
DES-7200(config）# ip pim jp-timer
interval-seconds
Set the interval of sending the Join/Prune
message, in the range of 1 to 65535
seconds.
DES-7200(config）# no ip pim jp-timer
interval-seconds
Restore the setting to the default value,
or 60s.
6.3.28 Allowing the Last Hop Device to Switch from the Shared Tree to the
Shortest Path Tree
The last-hop device is allowed to switch from the shared tree to the shortest path
tree.
When the sending speed of a source is higher than equal to the transmission
speed, a PIM join message is triggered and a source tree is constructed. If the
final key word is defined, all the sources in this group use the shared tree. If the
transmission speed is lower than the threshold, the leaf device re-diverts to the
shared tree and sends a prune packet to the source.
To allow the last hop device to switch from the shared tree to the shortest path
tree, execute the following commands in the global configuration mode:
Command Function
DES-7200(config）# ip pim spt-threshold
Allow the last-hop device to switch from
the shared tree to the shortest path tree.
DES-7200(config）# no ip pim
spt-threshold
Disable this function.
6.3.29 Using the MIB of PIM-DM
Execute this command to use the MIB of PIM-DM. Otherwise, the MIB of PIM-SM
will be used.
To use the MIB of PIM-DM, execute the following command in the global
configuration mode:
Command Function
DES-7200(config）# ip pim mib
dense-mode
Use the MIB of PIM-DM.
DES-7200(config）# no ip pim mib
dense-mode
Use the MIB of PIM-SM.
