What is the first step in configuring VRRP on an interface?

1. #no shut

2. #ip address and subnetmask

3. #interface interface

4. #vrrp VRRP GROUP NUMBER ip GROUP VIRTUAL IP ADDRESS

The correct answer is: #interface interface

In configuring the Virtual Router Redundancy Protocol (VRRP) on an interface, the initial step involves selecting the specific interface that will participate in the VRRP group. By using the command that specifies the interface, the configuration process is directed toward that particular interface, enabling further VRRP-specific configurations to be added later. Once the interface is identified, subsequent commands can be executed to set up the IP address, configure VRRP parameters, and define the virtual IP address for the group. This first step is critical as it establishes the context for all following configurations related to VRRP on the chosen interface. The subsequent commands, such as configuring the IP address or VRRP settings, cannot be executed until the interface context is established; hence, selecting the interface is the necessary precursor to the entire configuration process.
