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.

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.
