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 205 Configuring the filtering of multicast source/group
Operation
Configure the filtering of multicast
source/group
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
You can set to filter the PIM neighbors on the current interface via the following
configuration.
Perform the following configuration in the PIM View.
Table 206 Configuring the filtering of PIM neighbor
Operation
Configure filtering of PIM neighbor
Remove the configuration of filtering
By default, no filtering rules are set.
Only the routers that match the filtering rule in the ACL can serve as a PIM
neighbor of the current interface.
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 PIM view.
