Multicast Routing Settings
(Available in Router mode only) With a multicast design,
applications can send one copy of each packet and
address it to a group of computers that want to receive it.
This technique addresses packets to a group of receivers
rather than to a single receiver. It relies on the network
to forward the packets to the hosts that need to receive
them. Common routers isolate all the broadcast (thus
multicast) traffic between the local and external networks;
however, the device provides multicast traffic pass-
through functionality. Click the Multicast Routing Settings
section to display its contents.
Enabled Select this option to enable multicast packet
pass-through between local and external networks
while the device is operating in Router mode. Multicast
intercommunication is based on Internet Group
Management Protocol (IGMP).
Multicast Upstream Select the source of multicast traffic.
Multicast Downstream Enter the destination(s) of
multicast traffic.
