Chapter 12: AI2524 X.25 Configuration Steps

Example: Simple Remote PVC Tunneling

In this example, a connection is established between two PVCs across a LAN. Because the connection is remote (across the LAN), the tun neling command is used. This example establishes a PVC between Router X, Serial 0, PVC 1 and Router Y, Serial 1, PVC 2. Keepalives are enabled to maintain connection notification. Figure 12-4 provides a visual representation of the configuration.

Configuration for Router X

service tcp-keepalives-in service tcp-keepalives-out interface serial 0

x25 pvc 1 tunnel 172.20.1.2 interface serial 1 pvc 2

Configuration for Router Y

service tcp-keepalives-in service tcp-keepalives-out interface serial 1

x25 pvc 2 tunnel 172.20.1.1 interface serial 0 pvc 1

Configure an XOT (Remote) PVC

A PVC can be connected to another router over a LAN with the XOT protocol. When the interfaces come up, a TCP connection is estab- lished to the router that is acting as the switch for the destination. All X.25 packets will be sent and received over this reliable data stream.
