Huawei quidway s7700 - Configuring the Interval for Sending Hello Messages

Applicable Environment
PIM switchs exchange Hello messages to set up neighbor relationships and negotiate various
control parameters.
The Switch under the control of default values can work normally. In the S7700, users can adjust
related parameters according to the specific network environment.
NOTE
If there is no special requirement, default values are recommended.
Pre-configuration Tasks
Before adjusting control parameters for maintaining neighbor relationships, complete the
following tasks:
l Configuring a unicast routing protocol
l Configuring Basic PIM-DM Functions
Data Preparation
To adjust control parameters for maintaining neighbor relationships, you need the following
data.
No.
Data
1 Timeout period of the neighbor
2 Interval for sending Hello messages
3 Maximum delay for triggering Hello messages
4 Number or name of the ACL used to filter PIM neighbors
5.5.2 Configuring the Interval for Sending Hello Messages
The interval for sending Hello messages can be set either globally or on an interface. The
configuration in the interface view is prior to the configuration in the PIM view. When the
interval is not configured in the interface view, the configuration in the PIM view takes effect.
Context
Do as follows on the PIM-DM switch:
NOTE
The configuration involves the following 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.
