Showing HSRP State Information
Problem
You want to see current HSRP information, such as which router is primary.
Solution
To view the HSRP information, use the following EXEC command:
Router2#show standby
You can view the HSRP information for a specific interface with the following EXEC command:
Router2#show standby

Use the keyword brief to show an overview of HSRP information:
