l PIM silent is applicable only to the interface directly connected to the host network segment
that is connected only to this switch.
CAUTION
If PIM silent is enabled on the interface connected to a switch, the PIM neighbor relationship
cannot be established and a multicast fault may occur.
If the host network segment is connected to multiple switchs and PIM silent is enabled on
multiple interfaces of the switchs, these interfaces do not send Assert messages. Therefore,
multiple interfaces that forward multicast data exist in the user network segment. A multicast
fault thus occurs.
Pre-configuration Tasks
Before configuring PIM silent, complete the following tasks:
l Configuring a unicast routing protocol to make the network reachable
l Configuring PIM-DM
l Configuring IGMP
Data Preparation
To configure PIM silent, you need the following data.
No.
Data
1 Number of the interface connected to hosts
5.10.2 Configuring PIM Silent
After the interface is configured with PIM silent, it is forbidden to receive or forward any PIM
protocol packet. All PIM neighbors and PIM state machines on this interface are deleted. Then,
this interface automatically becomes the DR. IGMP on the interface is not affected.
Context
Do as follows on the interface connected to the host network segment:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface interface-type interface-number
The interface view is displayed.
