Configuring Routing Devices 119 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.
