Configuring Sending Interval for the Hello Packets
After PIM is enabled on an interface, it will send Hello messages periodically on the
interface. The interval at which Hello messages are sent can be modified according to
the bandwidth and type of the network connected to the interface.
Perform the following configuration in Interface view.
Table 343 Configuring hello message interval on an interface
Operation
Configure the hello message interval on an interface
Restore the interval to the default value
The default interval is 30 seconds. You can configure the value according to different
network environments. Generally, this parameter does not need to be modified.
This configuration can be performed only after PIM (PIM-DM or PIM-SM) is enabled in
Interface View.
Configuring the Filtering of Multicast Source/Group
You can set to filter the source (and group) address of multicast data packets via this
command. When this feature is configured, the router filters not only multicast data,
but the multicast data encapsulated in the registration packets.
Perform the following configuration in the PIM view.
Table 344 Configuring the filtering of multicast source/group
Operation
Configure the filtering of multicast source/group source-policy acl_number
Remove the configuration of filtering
If resource address filtering is configured, as well as basic ACLs, then the router filters
the resource addresses of all multicast data packets received. Those not matched will
be discarded.
If resource address filtering is configured, as well as advanced ACLs, then the router
filters the resource and group addresses of all multicast data packets received. Those
not matched will be discarded.
Configuring the Filtering of PIM Neighbor

configuration.
Perform the following configuration in the PIM View.
Table 345 Configuring the filtering of PIM neighbor
