Since Multicast packets are forwarded according to the preceding information, 
this table is the key for IP Multicasting.

Type “N” on the Multicast Configuration menu to display the PIM 
Neighbor. The IAD displays the neighbor for each interface and its 
expiration times.

Press any key to continue.

This section describes the steps required to configure Network Address 
Translation (NAT).

NAT multiplexes traffic from the internal network and presents it to the 
Internet as if it is from a single source that has only one IP address.

The NAT Local Server may be configured with a range of both TCP and 
UDP ports, which benefits applications including video conferencing and 
multi-user games.

Setting up IP networks without NAT may be complex—each requires an IP 
address, subnet mask, a DNS address and a default router. 

NAT reduces this complexity by

•

Modifying IP addresses and checksum without affecting traffic

•

Automatic network configuration when using DHCP

•

Packet-level filtering and routing

•

Traffic logging

Refer to the NAT Application Note in Appendix C for further information.

RPF Neighbor

IP address of the upstream PIM neighbor.

Outgoing Interfaces

List of the outgoing interfaces to which the multicast packet 
will forward.

Pruned

If an outgoing interface is Pruned, this means that the interface 
received a PIM Prune message.
