Enable HSRP on a Router

Description : This lab exercise demonstrates the necessary commands to enable the HSRP on a router.

HSRP is one of the so called FHRP or “First Hop Redundancy Protocols”. The other two FHRP protocols that are popularly known are VRRP (Virtual Router Redundancy Protocol) and GLBP (Gateway Load Balancing Protocol). In the labs, we cover HSRP.

The standby ip interface configuration command activates HSRP on the configured interface. If an IP address is specified, that address is used as the designated address for the Hot Standby group. If no IP address is specified, the address is learned through the standby function. 

Note 1: If both routers are set to the same priority, then the first router to come up will be the active router. The labs provide hands-on experience in configuring HSRP using Cisco routers and verifying the HSRP configuration. 

Note 2: When replying to traceroute command, the IP address of the physical interface is used, not the virtual IP address. Similarly, as per Cisco website, when a response for traceroute is received from a hop that runs HSRP, the reply must contain the active physical IP address and not the virtual ip address.
