4.3.3 Known Multicasts

In this frame you define how the device sends packets with a known MAC/IP
Multicast address that was learned through IGMP Snooping.
Prerequisite: In the Switching:Multicasts:Global Settings dialog,
the IGMP Snooping mode is selected.
Parameter Meaning
Send to query and The device sends the packets with a
registered ports known MAC/IP Multicast address to all
query ports and to registered ports.
This standard setting sends all Multi-
casts to all query ports and to regis-
tered ports. The advantage of this is
that it works in most applications with-
out any additional configuration.
Application:
"Flood and Prune" routing in PIM-DM.
Send to registered The device sends the packets with a
ports known MAC/IP Multicast address to
registered ports. The advantage of this
setting, which deviates from the stan-
dard, is that it uses the available band-
width optimally through direct
distribution. It requires additional port
settings.
Application:
Routing protocol PIM-SM.
