MicroNugget: How to Use IPv6 and the Gateway Load Balancing Protocol

In this video, Keith Barker covers the Gateway Load Balancing Protocol. GLBP is a first hop redundancy protocol that no enterprise network should live without. Keith explains what GLBP actually does, how it goes about doing it, how to configure it, and how to verify that it's working.

Gateway Load Balancing Protocols provide fault-tolerant gateways through redundancy at the first hop. In other words, GLBP is how a device that's looking to leave its local network can reliably get access to the group of devices that service its traffic with one virtual address.

One PC that uses one switch to access the Internet won't need GLBP. But once you've got a group of load-balancing devices supporting a subnet, GLBP ensures traffic keeps moving.

The important thing about GLBP is that even if one of a group of gateway load-balancing devices dies while servicing a given PC, as long as the PC knows the address it should be using as a virtual gateway to get out, the group of remaining devices can still support it.
