DI-206 ISDN Remote Router
36 Configuration and
Management
•
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 communications
between this router and other router(s) on the LAN.
•
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 change) to an adjacent router.
The adjacent router must be using the same protocol. Setting this to
