Configuring a X.25 Node

Configure Neighbor Gateways

Configure Neighbor Gateways

Use the next two screens only if you are configuring a node that is on an an X.25 network as a gateway. In this case, the local node needs to know the identity of any neighbor gateways.

Gateways that are on the same network are called neighbor gateways. A non-gateway node on an X.25 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.) If a node on the X.25 network is trying to access a node on a remote network, it needs to know the identity of its neighbor gateways. When you configure an X.25 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 specific gateway configured for the destination network. The default gateway will then attempt to locate the destination of the message.
