Configuring and implementation of HSRP on GNS3 with live link failure simulation

Hot Standby Router Protocol 

Introduction:

HSRP is  routing protocol HSRP stands for HOT STANDBY ROUTER PROTOCOL, it provides the network redundancy for the IP networks, it’s a dynamic router redundancy mechanism. It’s a Cisco proprietary protocol which provides redundancy for local subnets. HSRP has a good feature like we configure two or more routers as a standby routers and only single router works as active router. Active router responsible for forwarding the traffic. If the active router fails,

 standby router will takeover the responsibilities for the active router. HSRP offers unique advantages and some limitations. This protocol reveals deep dive into the functions, benefits, and real-world data, HSRP to help you understand the best suited for the real network needs. HSRP acts as a backup plan ensure that if the primary router fails another seamlessly takes over the responsibility of the primary router. It is a redundancy protocol that ensures high availability in network environment.

 It has 2-versions like version 1 & 2

 version 1 : The messages are multicast at 224.0.0.2 and uses the UDP port 1985. This version allows group number range from 0 to 255. 

version 2 : The messages are multicast at 224.0.0.102 and uses the UDP port 1985. This version allows group number range from 0 to 4095.

Capability	Version 1	Version 2
Hello timer units	Seconds	Milliseconds
Supports both IPv4 and IPv6	No (only IPv4)	Yes
Number of groups supported	256 (from 0 to 255)	4096 (from 0 to 4095)
Virtual MAC (-- or --- is the HSRP group number in HEX)	0000.0C07.AC--	0000.0C9F.F---
Multicast address	224.0.0.2	224.0.0.102

 Here in the video solution I explained the link failure simulation only there you can edit the timers and preempt..

That is based on the delaying the pinging..

Hopeful this very useful I think
