Table3-10 Configuring IP Routing to the AIC with an Unnumbered IP Address
Table3-11 Configuring IP Routing to the AIC without an Unnumbered IP Address
Command Purpose
Step1
Router(config)# ip route network-number network-mask
{IP address | interface} [distance] [name name]
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:
Router(config)#ip route 10.5.5.2
255.255.255.255 serial2/0
Step2
Router(config)# interface serialslot/port
Enter serial interface mode. Enter the slot in which
the AIC is installed and port 0.
Step3
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:
Router(config-if)# ip unnumbered
FastEthernet 0/0
Step4
Router(config-if)# exit
Exit serial interface mode.
Command Purpose
Step1
Router(config)# interface serialslot/port
Enter the serial interface mode. Enter the slot in
which the AIC is installed and the port 0.
Step2
Router(config-if)# ip address ip-address network-mask
Specifie the IP address and mask of the router’s
serial interface to the AIC. For example:
Router(config)# ip route 10.5.5.1
255.255.255.0
Step3
Router(config-if)# exit
Exits the serial interface mode.
