addresses. The NBX system uses Ethernet multicast addresses to
implement some system features.
If you have telephones connected to the network through a
low-bandwidth link, such as an ISDN connection, you can configure them
so that they do not generate multicast traffic (
Table 27
). For more
information, see the
NBX Administrator’s Guide
. You must still filter
multicasts to ensure that multicasts generated by other NBX devices are
not propagated through the low-bandwidth link.
