Protocols such as Virtual Router Redundancy Protocol (VRRP) or Hot Standby Router Protocol (HSRP) allow multiple switches to cooperate in providing continuous network availability. Network redundancy is essentially about having backup methods in place to keep your network up and running, regardless of hardware or software failures. Imagine if your primary pathway goes dark. In this tech paper, you will learn about the key protocols for building a redundant network and discover—based on five examples—how to design highly available three-tier or two-tier networks using LANCOM products. This paper is part of the series “switching solutions“. By connecting a switch to two. The WAN connectivity is pretty solid with dual-ISPs at each location connected to 2 44XX ISR Routers with HSRP redundancy. All switches are SG200-class and most of them are daisy-chained with a single 1GB uplink to an adjoining. 1:1 redundancy is used to assign active and standby roles to specific switches in the stack. Ethernet networks rely on this flood-and-learn behavior to work. It is straightforward to understand when there is a very simple topology with only. How to establish redundacy between these two switches so that if One link fails, the other will take over.
