134 CHAPTER 6: MULTICAST PROTOCOL
Configuring the Maximum Number of PIM Neighbor on an Interface
You can limit the PIM neighbors on an interface. No neighbor can be added any
more when the limit is reached.
Perform the following configuration in the PIM view.
By default, the PIM neighbors on the interface are limited to 128.
If the existing PIM neighbors exceed the configured value during configuration,
they are not deleted.
Displaying and Debugging PIM-DM
Execute the display command in all views to display the running of PIM-DM
configuration, and to verify the effect of the configuration.
Execute debugging command in user view for the debugging of PIM-DM.
