PIM-DM Setup
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. In the left panel, click Layer 3 IP Networking .
2. In the top panel, click PIM-DIM Interface Configurations.
3. Select the interface and click Edit.
4. Configure these fields.

Static Router Port Settings
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.
The purpose of a router port is to enable UDP multicast packets and IGMP multicast group
membership messages to reach multiple ports of a multi-port router. Routers do not implement
IGMP snooping or transmit/forward IGMP report packets. Thus, forwarding all IP UDP multicast
packets to a static router port on the ZT 8101 switch guarantees that all ports of a multi-port router,
which are attached to the switch, can reach all multicast group members through the attached
router's other ports.
A router port interacts with multicast packets in these ways:
130
Field
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.
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.
Disables or enables PIM-DM for this IP interface. The default is Disabled.
