Chapter 3 Configuring with the Command-Line Interface Configuring the NM-AIC-64, Contact Closure Network Module Table 3-10 Configuring IP Routing to the AIC with an Unnumbered IP Address Step 1 Command Router(config)# ip route network-number network-mask {IP address | interface} [distance] [name name] Purpose Establish the discrete IP route and mask on the router's serial interface. The arguments have the following meanings: network-number-IP address of the target network or subnet. network-mask-Network mask that lets you mask network and subnetwork bits. IP address-Internet address of the next hop that can be used to reach that network in standard IP address notation. Example: 10.1.1.1. interface-Network interface to use. distance-(Optional) An administrative distance, which is a rating of the trustworthiness of a routing information source, such as an individual router or a group of routers. name name-(Optional) Name of the user profile. Example: Step 2 Step 3 Router(config)#ip route 10.5.5.2 255.255.255.255 serial2/0 Router(config)# interface serialslot/port Enter serial interface mode. Enter the slot in which the AIC is installed and port 0. Router(config-if)# ip unnumbered type interface-number Enable IP processing on the serial interface to the AIC without assigning an explicit IP address to the interface. The type and interface-number arguments indicate another interface on which the router has an assigned IP address. The other interface cannot be an unnumbered interface, because only an interface that has its own IP address can be used to "lend" its IP to the serial port. Enter, for example: Step 4 Router(config-if)# exit Router(config-if)# ip unnumbered FastEthernet 0/0 Exit serial interface mode. Table 3-11 Configuring IP Routing to the AIC without an Unnumbered IP Address Step 1 Step 2 Command Router(config)# interface serialslot/port Router(config-if)# ip address ip-address network-mask Purpose Enter the serial interface mode. Enter the slot in which the AIC is installed and the port 0. Specifie the IP address and mask of the router's serial interface to the AIC. For example: Step 3 Router(config-if)# exit Router(config)# ip route 10.5.5.1 255.255.255.0 Exits the serial interface mode.
