Assigning a Logical Address to an Interface on a Router

What command is used to assign a logical address to an interface when configuring a router?

a) router(config-if) b) router(config-router) c) router(config-address) d) router(config-logical)

Answer:

The command used to assign a logical address to an interface when configuring a router is router(config-if).

When configuring a router, it is essential to assign a logical address to its interfaces. This allows the router to communicate with other devices on the network. To assign a logical address, the command 'router(config-if)' is used.

Explanation:

When configuring a router, the command used to assign a logical address to an interface is 'router(config-if)'. This command is utilized in the interface configuration mode, which can be accessed by entering the 'interface' command followed by the interface's name or number. Once in the interface configuration mode, the command 'ip address' is used to assign the logical address, along with the desired IP address and subnet mask.

For example:

router(config)# interface gigabitEthernet0/0

router(config-if)# ip address 192.168.1.1 255.255.255.0

By following these steps, you can effectively assign a logical address to an interface on a router, ensuring seamless communication within the network.
