Configuration Information
X.25 recognizes an incoming call for XTP based on the node addresses configured
for XTP.Therefore, in order to transport X.25 traffic between the X.25 nodes, you
must configure X.25 to map to the data terminal equipment (DTE) address and IP
addresses of the routers to which the nodes are connected.
For example, in Figure 19, you configure X.25 clients on remote routers and on the
concentrator router.

Remote routers

in this example are the routers that connect the
X.25 clients to the TCP/IP network that is used to access the X.25 server; the

concentrator router

connects the X.25 server to the TCP/IP network that is used to
access the remote routers.
Note: When you configure XTP,if a router is connected to an X.25 switch, it is
considered to be DTE. If it is not connected to a switch, it is considered to
be DCE (Data Circuit-TerminatingEquipment).
Toconfigure a router for XTP, define the following information from the XTP config>
prompt and then restart the router:
vLocal DTEs
vPeer routers
