15 Configuring IP Unicast-Routing
This chapter contains basic IPUC configuration examples. To see details on the commands used
in these examples, or to see the outputs of the validation commands, refer to other references. To
avoid repetition, some Common commands, like configure terminal, have not been listed under
the Commands Used section.
15.1 Enabling Static Routing
This example shows the complete configuration required to enable static routing in a simple
network topology. Static routes are useful in small networks. They are simple solutions for
making a few destinations reachable. Large networks use dynamic routing protocols. A static
route is composed of a network prefix (host address) and a nexthop (gateway).
Router R1 is configured with three static routes, one for the remote network 10.10.12.0/24 and
one each for the loopback addresses ( host addresses ) of routers R2 and R3. In all three
routers, interface eth0 of router R2 is the gateway. Router R3 is configured with a default static
route that is equivalent to configuring separate static routes with the same gateway or nexthop
address. Router R2 has two routes, one for each of the remote routers' loopback address.
R1
DUT# configure terminal Enter the configure mode
DUT(config) # interface loopback 0 Specify the loopback as the interface you want to
configure.
DUT(config-if) # ip address 192.168.0.1/32 Configure the IP address on this interface and specify a
32-bit mask, making it a host address.
DUT(config-if) # exit Exit the Interface mode and return to Configure mode.
DUT(config) # ip route 10.10.12.0/24 10.10.10.2
DUT(config) # ip route 192.168.0.2/32 10.10.10.2
DUT(config) # ip route 192.168.0.3/32 10.10.10.2
Specify the destination prefix and mask for the network
for which a gateway is required, for example,
10.10.12.0/24. Add a gateway for each of them (in this
case 10.10.10.2 for all). Since R2 is the only next hop
available, you can configure a default route instead of
configuring the same static route for individual
addresses, see the configuration of R3.
