Routing Devices

If you have a low-bandwidth device on the LAN, such as an ISDN router,

you must update the device's routing table to filter NBX system multicast

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

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.
