MicroNugget: How to Use "HSRP" for High Availability

In this video, Keith Barker covers how end users can leverage default gateways on a customer network in a few different ways. These are used to get off the local area networks by utilizing several different mechanisms, one being hot standby routing protocol (HSRP).
A lot of behind the scenes work happens to ensure that you can always get off local area networks when you access the internet. These are known as default gateways, and this video briefly covers three: hot standby routing protocol, gateway load balancing protocol, and common address resolution protocol.
All three of these provide a key concept in the process known as “fault tolerance.” Keith walks through several diagrams to illustrate how these processes work as they interact between the routers, VLAN, IP addresses, and the network at large. Additionally, the video will show a live demonstration of these concepts in action.
