NEC NWA-008869-001 manual Setup procedure, Setting the digital private line T1

CHAPTER 5 EXAMPLES OF SETUP ON NETWORKS

DIGITAL PRIVATE LINE NETWORK EXAMPLE (T1)

Setup procedure

Setting the digital private line (T1)

Check that the WAN port has been set up properly, referring to “SETTING UP THE WAN PRIVATE LINE

(T1)”. Page 104

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.

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.

Setting for router A

Router # enable − config Enter

Router (config) # ppp profile router − a Enter

Router (config − ppp − router − a) # no ipcp request − local − dns Enter

Router (config − ppp − router − a) # exit Enter

Router (config) # interface FastEthernet0.0		Enter
Router (config − FastEthernet0.0) # ip address 192.168.1.1/24							Enter
Router (config − FastEthernet0.0) # no shutdown			Enter
Router (config − FastEthernet0.0) # interface Serial0.0					Enter
Router (config − Serial0.0) # ppp binding router − a				Enter
Router (config − Serial0.0) # ip unnumbered FastEthernet0.0						Enter
Router (config − Serial0.0) # no shutdown	Enter
Router (config − Serial0.0) #
