DES-7200 Configuration Guide Chapter 6 PIM-SM
Configuration
6-11
address must be reachable for the response to the correct Register-Stop
information in the RP. The address is generally a loop address of the interface. It
also can be other physical address. Such address must be advertised by unicast
route on the DR port.
To configure the source IP address of RPs, execute the following commands in
the global configuration mode:
Command Function
DES-7200(config)# ip pim
register-source { local_address |
Interface-type interface-number}
Configure the source IP address used in
RPs.
DES-7200(config)# no ip pim
register-source
Set the RPF interface address as the
source IP address of RPs.
6.3.24 Configuring the RP Suppression Time
This command configures the RP suppression time. It will modify the RP
suppression time defined on the DR. If the ip pim rp-register-kat is not
configured, defining the RP suppression time in the RP will change RP keepalive
period.
To configure the RP suppression time, execute the following commands in the
global configuration mode:
Command Function
DES-7200(config）# ip pim
register-suppression seconds
Configure the RP suppression time.
DES-7200(config）# no ip pim
register-suppression
Set the suppression time to 60 seconds.
6.3.25 Configuring the Detect Time of Null Register Packet
The source DR can send null register packet to the RP in a period of time before
the RP suppression time expires. This period is detect time, 5s by default.
To configure the detect time of null register packet, execute the following
commands in the global configuration mode:
Command Function
ip pim probe-interval interval-seconds
Configure the detect time.
interval-seconds: in the range of 1 to
65535 seconds.
no ip pim probe-interval
Restore the detect time to 5s.
Caution
The detect time should be less than half of RP suppression time. Moreover, the
3* RP suppression time plus detect time should be no more than 65535
seconds or otherwise the system issues a warning.
6.3.26 Configuring KAT Timer
The KAT timer is used for monitoring PIM RP.
To configure KAT timer, execute the following commands in the global
configuration mode:
