Chapter 8 Bridge Configuration for LAN-to-LAN
8.2 Bridge Ethernet Setup
Bridging is used to forward packets of unsupported protocols whose destination is not on the local
Ethernet to the WAN.
Basically, all non-local packets are bridged to the WAN, however, your Prestige applies a special
handling for certain IPX packets to reduce the number of calls, depending on the setting of the
Handle IPX field.
Table 8-1 describes the [Handle IPX] field settings.

Description
None Nothing is done to IPX traffic.
Client All RIP and SAP (Service Advertising Protocol) periodical response packets will not
trigger the call.
Server No RIP or SAP packets will trigger the call. In addition, during the time when the
ISDN line is down, your Prestige will reply to the servers watchdog messages on
behalf of remote clients. The period of time that your Prestige will do this is linked to
the [Ethernet Address Timeout] parameter in each Remote Node (see Remote Node
Configuration). When a remote Ethernet address is aged out, there is no need to
maintain its connection to the IPX server.
