Conﬁguring a LAN, Token Ring, FDDI, 100VG-AnyLAN, 100Base-T 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 LAN, Token Ring, FDDI,

100VG-AnyLAN, or 100Base-T 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 LAN, Token Ring, FDDI,

100VG-AnyLAN or 100Base-T nodes that are on the same network as a

neighbor gateway need to know the identity of any neighbor gateways.

When you conﬁgure a LAN, Token Ring, FDDI, 100VG-AnyLAN, or

100Base-T 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 gateways as default gateways. Messages for a

network will be routed to a 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 6-7 is displayed when

you press the

[Neighbor Gateways] key at the selected conﬁguration

screen for the LAN, Token Ring, FDDI, 100VG-AnyLAN, and

100Base-T via screen numbers 41, 49, 201, 296, and 306 respectively.
