IP Multicast Configuration
IP multicast forwarding is supported with an optional software license. Enter the
following command to determine whether the multicast license is enabled:
admin> get base igmp
[in BASE]
igmp-np-enabled = yes
The system sets this parameter to
yes
when the IGMP license is enabled for the
IP2000 network processor. If the license is not enabled, the system displays an error
message if you configure multicast forwarding on the IP2000. For information about
obtaining and enabling Lucent Technologies software licenses, contact your Lucent
sales representative.
IP multicast forwarding
IP multicast forwarding enables the Stinger to receive multicast transmissions from
multicast backbone (MBONE) routers and forward the transmissions to multiple
client interfaces.
A common use for IP multicast is to transmit streaming video across the Internet to
applications running on multiple PCs or set-top boxes (STB) for television sets, as
shown in Figure 8-1.
