Assigning an IP address to the serial interface and setting PPP
To establish an inter-LAN connection with a digital private line, assign an IP address to the serial interface
of WAN or set the IP address as unnumbered.
To establish an inter-LAN connection with a digital private line, assign an IP address to the serial interface
of WAN or set the IP address as unnumbered.
In this example, the two routers are connected together without assigning an IP address to the digital pri-
vate line of the routers, so that routers A and B operate as if they were a single router. For this reason, the
IP address of the serial interface of WAN is set as unnumbered, so that the address to be used by the In-
Skin Router itself when sending an IP packet to the digital private line is the one assigned to the FastEth-
ernet 0.0 interface of LAN1.
To start PPP on the serial interface, associate the user-defined PPP profile (in this example, “router-a” and
“router-b”) with the serial interface. Use the PPP profile command to create a profile. Then, use the ppp
binding command to associate the created profile with the T1 interface.
Set the LAN addresses of routers A and B according to their respective networks.
