458 CHAPTER 43: PIM-DM CONFIGURATION
Perform the following configuration in system view.
Using undo pim command, you can, and back to system 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.
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.
This command also filters multicast data encapsulated in registration packets.
If this command is executed for a second time, the previous configuration will be
overwritten by the new configuration.
Configuring the Filtering
of PIM Neighbor
You can configure basic ACLs to filter the routers which can be PIM neighbors of
the current interface.
Perform the following configuration in the interface view.
Configuring the
Maximum Number of
PIM Neighbor on an
Interface
The maximum number of PIM neighbors of a router interface can be configured to
avoid exhausting the memory of the router or router faults. The maximum number
of PIM neighbors of a router is defined by the system, and is not open for
modification.
Perform the following configuration in the interface view.
