DI-308 ISDN Remote Router

The parameters are described below:
•
IP Address – This is the IP address for the router on the network to which this
interface is connected.
•
Netmask – This is a 32-bit bit mask that shows how the IP address is to be
divided into network, subnet and host parts. The netmask has ones in the bit
positions in the 32-bit address which are to be used for the network and subnet
parts, and zeros for the host part. The mask should contain at least the standard
network portion (as determined by the address's class), and the subnet field
should be contiguous with the network portion.
•
Forwarding (LAN) – This enables or disables forwarding between or among
interface(s).
•
State (ISDN) – This is a link method between this interface and adjacent
router(s). The methods are described:
1. Auto – This obtains and utilizes the IP address assignment from your ISP
(Internet Service Provider).
2. Disable – This disables this interface.
3. IP Stack – This enables this interface, and the IP address used will be the
value of the parameter, IP Address.
4. Unnumber – This utilizes a method of connecting this router with adjacent
routers, without having to define an IP network prefix between them. The
adjacent routers must have UNNUMBER capability too.
•
Routing Protocol – This is a distance vector routing protocol. RIP is an Internet
standard Interior Gateway Protocol defined in RFC 1058 and RFC 1723. Routing
information is sent periodically (each 30 seconds, or triggered by topology
