8-2 IP-Router Setup
IP Routing Setup
IP Routing in the General Setup dialog box must be enabled for this dialog box to appear. Then,
choose IP Routing Setup from the Setup menu on the SPEEDLAN Configurator. This dialog box
must be completed before saving any configuration in which IP Routing has been enabled. Saving
the configuration with incomplete entries in the route table will make the SPEEDLAN 8500
IDU inoperable. Enter the appropriate information as described below:
Default Router (IP Address)
This entry should be set to the IP address of the default router that the SPEEDLAN 8500 IDU
is to use when it does not know where to route a particular IP packet.
Default Router Interface
This entry should be set to the interface to which the default router is connected.
Preferred IP Address
From time to time routers will transmit unsolicited IP packets such as SNMP Traps, Syslog,
RIP, or IP ARP packets. Most routers randomly use one of the IP addresses from one of the
router's interfaces as the source IP address for these packets. On the IDU you can specify
the source IP address that you prefer to use for these packets.
