PIM Dense
1
The interval can be set between 3 and 65535 seconds, and it should not be less than 3.5 times
the hello timer value. The default value is 105 seconds.
To apply a PIM neighbor timeout value of 360 seconds to all ports on the device operating with
PIM, enter the following.
Brocade(config)# router pim
Brocade(config-pim-router)# nbr-timeout 360
Syntax: [no] nbr-timeout seconds
The default is 105 seconds. The range is 3-65535 seconds.
Modifying hello timer
This parameter defines the interval at which periodic hellos are sent out PIM interfaces. Devices
use hello messages to inform neighboring devices of their presence. The interval can be set
between 1 and 3600 seconds, and the default rate is 30 seconds.
To apply a PIM hello timer of 120 seconds to all ports on the device operating with PIM, enter the
following.
Brocade(config)# router pim
Brocade(config-pim-router)# hello-timer 120
Syntax: [no] hello-timer 1-3600
The default is 30 seconds.
Modifying prune timer
This parameter defines how long a PIM device will maintain a prune state for a forwarding entry.
The first received multicast interface is forwarded to all other PIM interfaces on the device. If there
is no presence of groups on that interface, the leaf node sends a prune message upstream and
stores a prune state. This prune state travels up the tree and installs a prune state.
A prune state is maintained until the prune timer expires or a graft message is received for the
forwarding entry. The default value is 180 seconds.
To set the PIM prune timer to 90, enter the following.
Brocade(config)# router pim
Brocade(config-pim-router)# prune-timer 90
Syntax: [no] prune-timer seconds
The default is 180 seconds. The range is 60-3600 seconds.
NOTE
The prune timer should always be configured in multiples of 30 within the range of 60-3600. When
you assign any other value, the prune timer will be changed to the next upper limit in the running
configuration.
For example, if you assign a prune timer for 70, which is between 60 and 90, the prune timer will be
set to 90 in the running configuration.
Modifying the prune wait timer
The prune-wait command allows you to configure the amount of time a PIM device will wait before
stopping traffic to neighbor devices that do not want the traffic. The value can be from zero to
fifteen seconds. The default is three seconds. A smaller prune wait value reduces flooding of
unwanted traffic.
