Conﬁguring a Point-to-Point Node

To Conﬁgure Neighbor Gateways

You need to visit the next two screens only if you are conﬁguring a

non-gateway node that is on the same network as a gateway. In this

case, the non-gateway node needs to know the identity of any neighbor

gateway. Neighbor gateways can be either full or half gateways.

Gateways that are on the same network are called neighbor

gateways. A non-gateway node on a Point-to-Point network may need

to go through a neighbor gateway in order to send messages to an

entirely different network. (Two nodes are on the same network if the

network portion of their IP addresses are the same.) All Point-to-Point

nodes that are on the same network as a neighbor gateway need to

know the identity of any neighbor gateways. When you conﬁgure a

Point-to-Point node, you enter into its conﬁguration the identity of any

accessible neighbor gateways that share the same network. The

identiﬁed gateways may be either full or half gateways.

You may designate one gateway as a default gateway. Messages for a

network will be routed to the default gateway if there is no gateway

conﬁgured for the destination network. The default gateway will then

attempt to locate the destination of the message.

To Identify Neighbor Gateways (If Any Are

Present)

The Neighbor Gateways screen (#152) in Figure 7-3 is displayed when

you press the

[Neighbor Gateways] key at the Point-to-Point Link

Conﬁguration screen (#44) in Figure 7-2.
