7.7.5 Configuring PIM Neighbor Filtering

To prevent some unknown devices from being involved in PIM, filtering PIM neighbors is
required. An interface sets up neighbor relationships with only the addresses matching the
filtering rules and deletes the neighbors unmatched with the filtering rules.
Context
To prevent some switch from being involved in the PIM protocol and prevent the switch from
becoming the DR, filtering PIM neighbors is required.
Do as follows on the switch enabled with PIM-SM:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface interface-type interface-number
The interface view is displayed.
Issue 01 (2011-10-26)
NOTE
This command is only supported by the S3700HI.
NOTE
The function of tracking downstream neighbors cannot be implemented unless all the PIM
switchs in the shared network segment are enabled with this function.
Configuration on an interface
1. Run:
system-view
The system view is displayed.
2. Run:
interface interface-type interface-number
The interface view is displayed.
The interface can be a VLANIF interface, or an Loopback interface.
3. Run:
pim hello-option neighbor-tracking
The function of tracking a downstream neighbor is enabled.
After this function is enabled, information about the downstream neighbor who has
sent a Join message and whose Join state does not times out is recorded.
NOTE
The function of tracking downstream neighbors cannot be implemented unless all PIM
switchs in the shared network segment are enabled with this function.
