摘要：In this paper, we are focusing on data link layer protocols. First, when designing a network, one of the most important things to focus on when is designing a network on how to deal with failure. A major part of this research is trying to explore First Hop Redundancy Protocol and providing as much redundancy and security into the network as financially possible, while also maintaining performance and manageability. From the client’s view, the first set of the network they deal without, outside of their local subnet, is the default gateway; if this gateway goes down, then access to an entire network outside their own network would go down. One good ways to deal with this is to implement a first hop redundancy protocol. On Cisco equipment, there are a couple of different options to choose from, including Hot Standby Router Protocol (HSRP), Virtual Router Redundancy Protocol (VRRP) and Gateway Load Balancing Protocol (GLBP). This defines the complete overview and differences of these protocols.
