Which Cisco Internetwork Operating System (IOS) command would be used to define a static route for network
192.168.11.0 through default gateway 192.168.43.1?
A.
router(config)# ip route 192.168.11.0 255.255.255.0 192.168.43.1
B.
router# ip route 192.168.11.0 255.255.255.0 192.168.43.1
C.
router(config)# ip classless 192.168.43.1
D.
router(config)# ip default gateway 192.168.11.0 255.255.255.0 192.168.43.1
E.
router# ip default gateway 192.168.43.1
Explanation:
The router(config)# ip route 192.168.11.0 255.255.255.0 192.168.43.1 command would be used to define a
static route for network 192.168.11.0 through default gateway 192.168.43.1. Static routing is used to manually
configure routes to remote networks. The syntax of the ip route command is as follows:
ip route [destination_network] [mask] [next-hop_address or exit interface] [administrative_distance]
[permanent]
The parameters of the command are as follows:
destination_network: Defines the network that needs to be added in the routing table.
mask: Defines the subnet mask used on the network.
next-hop_address: Defines the default gateway or next hop router that receives and forwards the packets to
the remote network.
administrative_distance (AD): Static routes have an AD of 1, which can be changed to change the priority of
the route.
Static routing is often implemented in small yet stable networks where the number of routes is small and
manageable, and the network can benefit from the elimination of the traffic that dynamic routing protocols
would introduce. If this is the case, it is important that all routes be statically created, or else networking
problems can occur. For example, if in the diagram below no route to the 192.168.110.128/26 network on
Router 2 exists on Router 1, Host 1 will be unable to ping Host 2. The fact that Host 1 would still be able to ping
the S0/0 interface on Router 2 could obscure this missing route.
Host 1 will be able to ping the S0/0 interface of Router 2 because the 192.35.87.4/30 network will be in the
routing table of Router 1, being directly connected to Router 1. Directly connected routes are automatically
placed in the routing table. However, if you executed the show run command on Router 1, the output would
indicate that no route to the 192.168.110.128/26 exists:<output omitted>
interface Fa0/1
ip address 192.168.54.65 255.255.255.192
no shutdown
interface S0/0
ip address 192.35.87.5 255.255.255.252
no shutdown
The option router# ip route 192.168.11.0 255.255.255.0 192.168.43.1 is incorrect because the ip route
command should be configured in the global configuration mode.
The option router(config)# ip classless 192.168.43.1 is incorrect because the ip classless global configuration
mode command allows a router to accept and forward packets for subnets that are not directly connected. The
packets are forwarded to the best available supernet route.
The option router(config) # ip default gateway 192.168.11.0 255.255.255.0 192.168.43.1 is incorrect because
the ip default gateway command is used to define the default gateway address when IP routing is disabled in
the network.
