5.9.1 Establishing the Configuration Task
After basic functions of PIM-DM are configured, you can set the holdtime of the Assert state as
required.
Applicable Environment
When a PIM-DM switch receives multicast data through a downstream interface, it indicates
that other upstream switchs exist in the network segment. The switch sends Assert messages
through the interface to elect the unique upstream switch.
Switchs can work normally under the control of the default parameter values. Users can adjust
related parameters according to the specific network environment.
NOTE
If there is no specific requirement, default values are recommended.
Pre-configuration Tasks
Before adjusting control parameters for Assert, complete the following tasks:
l Configuring a unicast routing protocol
l Configuring Basic PIM-DM Functions
Data Preparation
To adjust control parameters for Assert, you need the following data.
No.
Data
1 Period for keeping the Assert state
5.9.2 Configuring the Period for Keeping the Assert State
The device that fails in the election prevents its downstream interface from forwarding multicast
data. After the holdtime of the Assert state expires, the downstream interface can forward
multicast data.
Context
Do as follows on the PIM-DM switch:
NOTE
The configuration involves the following two cases:
l Global configuration: It is valid on each interface.
l Configuration on an interface: The configuration on an interface takes precedence over the global
configuration. If the configuration on an interface is not done, the global configuration is used.
Procedure
l Global Configuration
