Below we will be an example to illustrate the dynamic IP address the specific configuration. In this example we will also isp-configuration of the router and client. Dynamic IP in the client's configuration on the router, the router from the client side of the isp made public network router's IP address. Router and the client also activated DHCP servers and NAT functionality.
Network topology are as follows:
ISP-router configuration
Set System called isp.
Add Token ring interface.
Config (only)> set hostname isp
Host name updated successfully
Config (only)> add device tr-2
Device Slot # (1-4) [1]?
Device Port # (1-2) [1]?
Adding 2-port IBM Token Ring device in slot 1 port 1 as interface # 4
Use "net 4" to configure 2-port IBM Token Ring parameters
WAN I set up to support remote credited.
WAN I add in the dial-in circuit.
MB3-430Config (only)> set data v34 2
Config (only)> add device dial-in
Enter the number of PPP Dial-in Circuit interfaces [1]?
Adding device as interface 5
Defaulting data-link protocol to PPP
Base net for this circuit [0]? 2
Enable as a Multilink PPP link? [No]
Disabled as a Multilink PPP link.
Add more dial circuit interface (s)? (Yes or [No]):
Use "set data-link" command to change the data-link protocol
Use "net" command to configure dial circuit parameters
