Bridging Setup
This chapter shows you how to configure the bridging parameters of your Prestige.
7.1 Bridging
in
General
Bridging bases the forwarding decision on the MAC (Media Access Control), or hardware address, while
routing does it on the network layer (IP or IPX) address. Bridging allows the Prestige to transport packets of
network layer protocols that it does not route, e.g., SNA, from one network to another. The caveat is that,
compared to routing, bridging generates more traffic for the same network layer protocol, and it also
demands more CPU cycles and memory.

For efficiency reason, do not turn on bridging unless you need to support protocols other than IP and IPX
on your network. For IP and IPX, enable the respective routing if you need it; do not bridge what the
Prestige can route.

Ethernet
Setup
Basically, all non-local packets are bridged to the WAN, however, your Prestige applies special handling
for certain IPX packets to reduce the number of calls, depending on the setting of the Handle IPX field.
