The Bridge/Router Menu shows the MAC address for the unit you are
viewing and current 10BASE-T and Ethernet Bridge Mode link status.
See "View Status" (page 41) for more information on the Statistics menu.
Through the Bridge/Router Configuration menu, you can configure the
Megabit Modem as either a bridge to forward Ethernet data based on
MAC addresses or as a router to route Ethernet data based on IP addresses.
You must configure both Megabit Modems (local and remote) with the same
mode (both as bridges or both as routers).
Bridge mode can be a less secure method of sending data because the desired
MAC address is broadcast over the network, but it allows protocols other than
IP to be forwarded. Router mode provides security by statically mapping route
entries. Routing can prevent eavesdropping and provide broadcast filtering.
Select either the "Configure as a Bridge" section (page 31) or the "Configure as
a Router" section (page 34).
After you change Bridge/Router Configuration or the SNMP Configuration
options, "Reset the Ethernet bridge" (page 40) to make the changes effective.
