Type “Y” on the DHCP Server Configuration menu to delete a DHCP 
Assignment Entry. The IAD prompts you for the DHCP entry index number 
to delete.

Type the index number to delete and press Enter.The IAD deletes the 
assigned IP address from the Display DHCP Server Assigned Addresses 
command and saves the new configuration.

Multicast (point-to-multipoint) is a communication feature that allows a 
source host to send a message to a group of destination hosts. Multicasting 
reduces traffic on the local network by sending only one (multicast) packet 
out to a higher-bandwidth relay point.

Multicasting differs from broadcasting in that a receiver must join a multicast 
group to receive group messages. Each multicast group has its own group 
address, which is a Class D IP address—224.0.0.0—239.255.255.255.

Type “M” on the Main menu (Figure 2.2) to display the Multicast 
Configuration menu. 

The Multicast Configuration menu contains commands to configure IP 
Multicast Routing. The IAD displays the Multicast Configuration menu only 
when DHCP Server is enabled and the IAD has been reset.

When you have completed multicast configuration, reset the IAD for the 
changes to take effect.

To enable or disable global IP Multicasting, follow the steps below:

Type “E” on the Multicast Configuration menu (Figure 4.57) to select 
Enable/Disable Global IP Multicasting.
