Logical Relationships Between Configuration Tasks; Configuring Basic Pim-Dm Functions - Huawei Quidway S9300 Configuration Manual - Multicast

3 PIM-DM Configuration
Controlling Multicast Source Forwarding
You can set Keepalive period and rules for filtering multicast sources.
Changing the Values of Neighbor Control Parameters
You can set the interval for sending Hello messages, the period for keeping neighbors reachable,
and the maximum delay for triggering Hello messages.
Changing the Values of Forwarding Control Parameters
The forwarding control parameters are classified into the following types:
l
l
Changing the Values of State-Refresh Control Parameters
You can enable or disable State-Refresh, set the interval for sending PIM State-Refresh
messages, set the waiting period for receiving the next State-Refresh message, and set the TTL
value used to forward State-Refresh messages.
Changing the Values of Graft Control Parameters
You can set the interval for re-sending Graft messages.
Changing the Values of Assert Control Parameters
You can set the period for keeping an S9300 in Assert state. During this period, the S9300 that
fails in the election prohibits the downstream interface from forwarding multicast data. After
the period expires, the S9300 restores the forwarding of the downstream interface.

3.3 Logical Relationships Between Configuration Tasks

This section describes the logical relationships between the configuration tasks.
To make each configuration of PIM-DM take effect, you must configure the basic PIM-DM
functions. All other configuration tasks are optional and are not listed in sequence. You can
configure them as required..

3.4 Configuring Basic PIM-DM Functions

This section describes the applications of PIM-DM and method of configuring PIM-DM.
3-4
Parameters for controlling the forwarding relation, such as:
The period for keeping the Prune state of a downstream interface
–
Interval for sending Join messages
–
Interval for keeping the Prune state of a downstream interface
–
Whether the Hello message contains the Generation ID option
–
Parameters for controlling the Prune state, such as:
Delay from the time when the S9300 receives a Prune message from a downstream
–
S9300 to the time when the S9300 performs the prune operation
Period for overriding the prune operation
–
