Which command helps to display VRRP information about a router?

1. #show vrrp

2. #display vrrp

3. #show ip vrrp

4. #info vrrp

The correct answer is: #show vrrp

The command that effectively displays VRRP (Virtual Router Redundancy Protocol) information on a router is "#show ip vrrp." This command provides detailed insights into the VRRP configuration and status on the router, including information related to virtual routers, their state, priority, and the IP addresses associated with them. The correct command emphasizes the need for specifying the protocol type (in this case, IP) when querying VRRP information, as VRRP operates at the network layer and relies on IP address configurations. By using this command, a network administrator can obtain critical operational data to monitor and troubleshoot VRRP setups. The other commands you encountered either specify the protocol incorrectly or don't adhere to standard Cisco command syntax for displaying VRRP-related information.
