3Com 10014298 manual Configuring the Filtering of Multicast Source/Group

Configuring PIM-DM 133

Perform the following configuration in VLAN interface view.

Table 140 Configure Hello Message Interval on an Interface

Operation	Command
Configure the hello message interval on an	pim timer hello seconds
interface
Restore the interval to the default value	undo pim timer hello

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 VLAN 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 141 Configuring the Filtering of Multicast Source/Group

Operation	Command
Configure the filtering of multicast	source-policy acl-number
source/group
Remove the configuration of filtering	undo source-policy

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 Neighbors

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 142 Configuring the Filtering of PIM Neighbors

Operation	Command
Configure filtering of PIM neighbor	pim neighbor-policy acl-number
Remove the configuration of filtering	undo pim neighbor-policy

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.
