PIM-DM Interface Configurations
The Protocol Independent Multicast - Dense Mode (PIM-DM) protocol should be used in networks
with a low delay (low latency) and high bandwidth because PIM-DM is optimized to guarantee
delivery of multicast packets, not to reduce overhead.
To configure PIM-DM for an IP interface
1. From the Main Menu, select Layer 3 - IP Networking Setup | PIM-DM Interface
Configurations and press Enter.
2. Configure these fields.

Hello Interval

Static Router Port
A static router port allows UDP multicast and IGMP packets to be forwarded to a designated port
regardless of VLAN configuration.
A router port functions within Layer 2 of the OSI model. A static router port is a port that has a
router attached to it. Generally, this router would have a connection to a WAN or to the Internet.
Establishing a router port will allow multicast packets coming from the router to be propagated
through the network. It also allows multicast messages coming from the network to be propagated
to the router.

Field
Specifies the cost for this path. The higher the assigned cost, the less likely
it is that multicast packets will be routed over this interface (provided that
other path options exist). Enter a value between 1—31. The default is 1.
Enables or disables DVMRP for this interface.
Field
Specifies the name of an IP interface that you want to configure for PIM-DM.
This must be a previously-defined IP interface. The IP Address field
displays the address associated with the IP interface.
Specifies the interval between sending Hello packets to other routers on the
network. The Hello messages are used by the router to determine whether it
is the root router on the delivery tree or not. If the router does not receive a
Hello message within the Hello Interval, it will begin transmitting Hello
messages to advertise its availability to become the root router. The range is
between 1—65535 seconds. The default is 30 seconds.
Disables or enables PIM-DM for this IP interface.
Specifies the interval for performing these tasks:
• Removing prune information from a branch of a multicast delivery tree.
• Flooding multicast messages to all branches of that delivery tree.
These two actions are equivalent. The range is between 1— 65535
seconds. The default is 60 seconds.
