74.2 Configuring PIM-DM
74.2.1 Modifying Timer
The routing protocol adopts several timers to judge the transmission frequency of Hello message and state-
refresh control message. The interval to transmit the Hello message affects whether the neighbor relationship
can correctly created.
Run the following commands in switch configuration mode to regulate the timer:
Command Purpose
ip pim-dm hello-interval
Sets the interval (unit: second) to send the
Hello message from the interface and the
neighbor.
ip pim-dm state-refresh origination-
interval
For the first-hop switch directly connecting
the source, the interval to send the state-
refresh message is only valid to the
configurations at the upstream ports. For the
following switches, the interval is the period
to receive and handle the state-refresh
message.
74.2.2 Designating the Version Number
PIM-DM of the router only supports PIM v2.
As PIM v1 is out of date, we supports PIM v2 by default. The command here only aims to be compatible with
the former in style.
Command Purpose
ip pim-dm version
version Configures PIM-DM version on the switch
logical port.
74.2.3 Configuring State-Refresh
The state-refresh control information of the PIM-DM is forwarded in management mode by default. The
configuration commands in interface configuration mode are effective only to the configurations at the
upstream ports when the first-hop switch directly connecting the source sends the state-refresh message
periodically. For the following switches, the interval is the period to receive and handle the state-refresh
message.
Command Purpose
no ip pim-dm state-refresh disable
Allows to send and receive the state-refresh
message on the port.
ip pim-dm state-refresh origination-
interval
Configures the interval to send and receive
the state-refresh message on the port.
74.2.4 Configuring Filtration List
PIM-DM does not set the filtration list by default. The referred filtration list includes the neighbor filtration list
and the multicast boundary filtration list. The filtration list requires to be configured in interface configuration
