ccna for cyber security.Both versions operate on UDP, with both the source and destination ports being 1985o, but version 1 uses multicast address 224.0.0.2 to send HSRP packets, while version 2 uses multicast address 224.0.0.102 to send HSRP packets.HSRP Message Types The messages sent by HSRP routers include the following 3 types.Hello: The Hello message informs other routers of the HSRP priority and status information of the router sending the Hello message.The HSRP router sends a Hello message every 3 seconds by default.Coup: Sends a Coup message when a backup router becomes an active router.Resign: When the active router is going down or when a higher priority router sends a Hello message, the activeThe active router proactively sends a Resign message.(7) HSRP Priority and Preempt The main purpose of the HSRP Preempt feature is to enable gateway redundancy so that when the active router fails, the backup route will preempt to become the active router. The HSRP protocol uses priority to determine which router becomes the active router. If a router has a higher priority than the other routers, that router becomes the active router. If the priority is the same, the router with the portThe default priority is 100, in the range of 0.255. preemption is not enabled by default. Configuring HSRP preemption ensures that the router with the higher priority becomes the active router at all times.(8) HSRP Port Tracking The port tracking feature enables a router to adjust the priority of an HSRP group based on the port status. When the key object being tracked becomes
