Intel ZT8101 PIM-DMInterface Configurations, Static Router Port, Using the Telnet Console

Using the Telnet Console

Field	Description
	Specifies the cost for this path. The higher the assigned cost, the less likely
Metric	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.
State	Enables or disables DVMRP for this interface.

3. Highlight APPLY and press Enter.

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.

Field	Description
	Specifies the name of an IP interface that you want to configure for PIM-DM.
Interface Name	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
Hello Interval	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.
State	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.
Join-Prune Interval	• 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.

3. Highlight APPLY and press Enter.

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.
