What command would you use to verify active GLBP information on a router?

1. #show glbp

2. #display glbp

3. #check glbp

4. #glbp status

The correct answer is: #show glbp

The command to verify active GLBP (Gateway Load Balancing Protocol) information on a router is indeed the one that begins with "show". The command specifically requested, "#show glbp", is the correct syntax used in Cisco IOS devices to display information about GLBP configurations and operational status. This command provides a comprehensive overview of the GLBP group, including members, priority, load balancing methodology, and the status of the virtual IP addresses associated with the protocol. By contrast, commands like "display glbp," "check glbp," or "glbp status" are not valid in Cisco IOS. They do not follow the established command structure that Cisco devices utilize, which adheres to a "show" command format for retrieval of status and configuration information. Therefore, the use of "show glbp" effectively aligns with the command guidelines of Cisco systems, ensuring users access the correct information regarding the active GLBP configurations.
