There are a few different types of transmission methods for IP packets with the most common being unicast. A Unicast packet, is a packet that is sent from a single source to a single destination.

Each device on the IP network within that subnet will receive a broadcast packet. An example of a broadcast is a DHCP request packet.
In my previous article, I went through the fundamentals of BGP and the basics of configuring BGP peers and advertising networks. In this article I will delve a little into just how powerful BGP route manipulation can be. First, let's take a look at the 4 typical redundancy scenarios that an organisation might use to establish their connection to their Internet Service Provider.
In the previous article, I talked a little about BGP and how it works. This article will go through the configuration BGP using both IPv4 and IPv6 addressing. For this article, I will use the following topology.
