PIM Configuration Commands
6-16
Use the undo pim timer hello command to restore the default value of the interval.
By default, a VLAN interface sends Hello messages at the interval of 30 seconds.
When the PIM-SM protocol is enabled on a VLAN interface, the switch will periodically
send Hello messages to the network devices supporting PIM. If the VLAN interface
receives Hello messages, it means that the VLAN interface has neighboring network
devices supporting PIM, and the VLAN interface will add the neighbors into its own
neighbor list. If the VLAN interface does not receive any Hello message from a
neighbor in its neighbor list within the specified time, the neighbor is considered to have
left the multicast group.
Examples
# Configure VLAN-interface 10 of the switch to send Hello message at the interval of 40
seconds.

View
PIM view
Parameters
acl-number: Number of advanced IP ACL, defining the rule of filtering the source and
group addresses. The value ranges from 3000 to 3999.
Description
Use the register-policy command to configure a RP to filter the register messages
sent by the DR in the PIM-SM network and to accept the specified packets only.
Use the undo register-policy command to remove the packet filtering configuration.
Examples
# Configure RP to filter register messages from the DRs and receive only register
messages whose multicast source is 10.10.0.0/16 and the multicast group
255.1.0.0/16.
