4. Every field requires high availability of network with the least probability of data loss. Therefore, redundancy should be involved as much as possible for network design. the high availability of network necessitates higher managerial and operational cost. Redundancy protocols substantially help to solve the problem . First Hop Redundancy Protocols (FHRPs) are implemented to overcome traffic loss from source to destination in network communications. The FHRPs include three protocols: Hot Standby Router Protocol (HSRP) Virtual Router Redundancy Protocol (VRRP) Gateway Load Balancing Protocol (GLBP). Introduction

5. The comprehensive data of the protocols, their working and comparison between them. The comparison indicates that which protocol is best in which scenario and which is best among the three protocols. These protocols work on layer 3 devices that are on the Transport layer. Cont…

9. First Hop Redundancy Protocol cont… Ability of a network to dynamically recover from the failure of a device acting as a default gateway is known as first-hop redundancy. First Hop Redundancy Protocols (FHRP) is a collection of protocols that permit a secondary gateway to take over all the responsibilities of primary default gateway router if it fails

11. First Hope Redundancy Protocol cont… Hot Standby Router Protocol (HSRP ) An actor that communicates through network has an HSRP protocol configured. there are two paths, one to be chosen for the transfer of the traffic. will choose that path which will have the highest priority and is active at that time

12. First Hope Redundancy Protocol cont… Virtual Router Redundancy Protocol (VRRP) An actor wants to communicate with the other actor over the network on which VRRP is configured . chooses path from available paths. R1 is the active router has the highest priority traffic will be forwarded through this router to R3 . If the Router1 is not active at that time so the VRRP protocol will transfer the traffic through Router2.

13. First Hope Redundancy Protocol cont… Gateway Load Balancing Protocol (GLBP) The GLBP is configured on the network so if an actor wants to communicate with the other actor. Router 1 is active and Router 2 is the standby router at the same time both routers can send the traffic to achieve the load balancing .

20. Conclusion cont.. After a detailed review of these protocols, we have concluded that GLBP outperforms HSRP and VRRP. It utilizes available resources more effectively than the other two protocols. When I consider the stability of networks or load balancing, GLBP gives the required provisions. These results are so essential for choosing the best suitable redundancy protocol even when our network goes large. FHRPs provide cheaper and simple redundancy features for networks

21. Conclusion I have compared these protocols according to some useful parameters like bandwidth consumption, CPU utilization and convergence time.
