Bridging Setup
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 641 to transport
packets of network layer protocols that the Prestige 641 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 reasons, 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 641 can route.
7.2 Bridge Ethernet Setup
Basically, all non-local packets are bridged to the WAN; however, your Prestige 641 applies special
handling for certain IPX packets to reduce the number of calls, depending on the setting of the Handle IPX
field.
This chapter shows you how to configure the
bridging parameters of your Prestige.
