7.10.2 Configuring the Period for Keeping the Assert State

The device that fails in the election prevents its downstream interface from forwarding multicast
data during the Assert state. After the holdtime of the Assert state expires, the downstream
interface can forward multicast data.
Context
Do as follows on all the switchs in the PIM-SM domain:

Data
Interval for holding the Assert state
NOTE
The configuration involves the following cases:
l Global configuration: It is valid on all the interfaces.
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.
Global Configuration
1. Run:
system-view
The system view is displayed.
2. Run:
pim
The PIM view is displayed.
3. Run:
holdtime assert interval
The interval for holding the Assert state is set.
The switch that fails in the election prevents the downstream interface from forwarding
multicast packets within the interval. After the interval expires, the downstream
interface starts to forward multicast packets.
