X.25 Network Interface Conﬁguration Screens

Neighbor Gateway Reachable Networks

Fields Neighbor gateway IP internet address

Enter the full network address of a gateway node (on

this network) that is to be used to reach other networks

(any network in the same internetwork other than the

network of which this node is a member). The network

portion of the address must be the same as that entered

on the IP Protocol Conﬁguration screen for the network

interface you are conﬁguring; however, the node portion

need not match.

There are two methods of entering an internet protocol

(IP) address within NMMGR:

1. Enter the fully qualiﬁed IP address (for example,

Class C, C 192.191.191 009)

2. Enter only the network (nnn) and node (xxx)

portions of the IP address as four positive integers

between 0 and 255 separated by periods or blanks

(for example, 15.123.44.98).

You need not enter the following items as NMMGR

will ﬁll these in:

– Class A, B, C

– Leading zeros for the network and node portion of

the IP address.

Addresses are made up of a network portion and a

node portion. The supported classes of network

addresses have the following forms:

Class C: C nnn.nnn.nnn xxx

Class B: B nnn.nnn xxx.xxx

Class A: A nnn xxx.xxx.xxx

where nnn is a value ranging from 000 to 255,

representing eight bits of the network portion of an

address and xxx is a value ranging from 000 to 255,

representing the node portion of the address.

Note that network and node values of all zeros or all

ones are not allowed. These are special values.
