Telco and ISP Dial Scenarios and Configurations

PPP Calls over X.25 Networks

User Setup for SLIP and Static IP Address

The following example shows a user setup for SLIP and a static IP address that stays with the user across all connections. Make sure your routing is set up to support this configuration, especially for large or multiple POPs.

staticallyslipme Password = "cisco" Service-Type = Framed, Framed-Protocol = SLIP, Framed-IP-Address = 1.1.1.13

Telnetting to a UNIX Host

The following example automatically uses Telnet to connect the user to a UNIX host. This configuration is useful for registering new users, providing basic UNIX shell services, or providing a guest account.

telnetme Password = "cisco" Service-Type = Login, Login-Service = Telnet, Login-IP-Host = 4.1.1.1

Automatic Rlogin to UNIX Host

The following example automatically uses rlogin to connect the user to a UNIX host:

rloginme Password = "cisco" Service-Type = Login, Login-Service = Rlogin, Login-IP-Host =4.1.1.2

If you want to prevent a second password prompt from being brought up, you must have the following two commands enabled on the router or access server:

rlogin trusted-remoteuser-source local

rlogin trusted-localuser-source radius

PPPCalls over X.25 Networks

Remote PCs stationed in X.25 packet assembler-disassembler (PAD) networks can access the Internet by dialing in to Cisco routers, which support PPP. By positioning a Cisco router at the corner of an X.25 network, ISPs and telcos can provide Internet and PPP access to PAD users. All remote PAD users that dial in to X.25 networks dial in to one Cisco router that allows PPP connections. Although connection performance is not optimal, these X.25 to PPP calls utilize installed bases of X.25 equipment and cost less to operate than connecting over the standard telephone network.

Note This dial-in scenario can also be used as an enterprise solution. In this case, an enterprise consults with a third-party service provider that allows enterprises to leverage exiting X.25 enterprise equipment to provide connections back into enterprise environments.
