DI-308 ISDN Remote Router

•Intf – This is the network interface containing the gateway that the packets will be forwarded through.

•State – This enables or disables a particular entry.

IP Static Route Examples

The IP Static Route Table shown in the example IP Static Route screen above has the first three entries configured for common implementations of static routing.

The first entry assumes that ISDN1 has a connection to the Internet and defines the default next hop router. If you use this router to connect to the Internet it is very important that you create an entry here that defines the default next hop router as your ISP. This configuration is also commonly used when RIP exchanges with other Internet routers (on ISDN1) are disabled.

The second entry shows how to configure static routes when there is another router on the LAN. The IP Address shown (202.12.125.0) is the network address for a branch office, for example. The Gateway Address (210.172.23.1) is the IP address to the LAN port on another router on the LAN that maintains an ISDN connection to the branch office.

The third entry is an example of an enterprise ISDN connection (through telephone lines) to another router, at a branch office for example. The IP Address is the network address of the branch office. The Gateway Address is the IP Address of the ISDN port on the branch office router. This configuration assumes there is a modem on ISDN2 maintaining a dial-up connection to the branch office.

IP Networking

Under the IP Configuration submenu, the IP Networking function can toggle to connect/disconnect this router from the entire IP network.

When IP Networking is disabled, all routing functions are stopped. The only IP Address the router will act on is its own, via Telnet for example.

Router Advertisement

When this option is enabled, the router will periodically send out ICMP packets that announce itself on the network. These ICMP packets are utilized by the Windows 98 or later operating system, which will automatically update the default gateway setting on the computer in which it is installed.

SNMP Agent Configuration

The Simple Network Management Protocol (SNMP), defined in STD 15, RFC 1157, is a protocol governing the management and the monitoring of IP network devices and their functions. The DI-308 supports the use of SNMP to acknowledge communication between management stations and itself. Basically, the DI-308,
