The depletion of IPv4 address space is upon us. 2012 is the year for current and aspiring network engineers to learn how to configure IPv6 routing protocols, specifically RIPng, EIGRP and OSPFv3. In this article, network engineer Sean Wilkins focuses on the basic configuration of RIPng for IPv6, helping you enter the world of IPv6 routing protocols.

With the wide scale implementation of IPv6 coming closer, it is important for any network engineer to learn the IPv6 routing protocols. This article by Networking Consultant Sean Wilkins walks you through the basic configuration of EIGRP for IPv6.

With the IPv6 Launch Day upon us, it is becoming more important for network engineers to become familiar with how to configure IPv6 routing protocols. This article by Networking Consultant Sean Wilkins focuses on the basic configuration of OSPFv3 for IPv6

Once you obtain a basic understanding of IPv6, the next logical step is to test out the different capabilities that exist within Cisco equipment and IOS. In this article, Cisco Professional Sean Wilkins explains the configuration of IPv6 addressing on a Cisco IOS device.

Learning IPv6 addressing may look daunting, but once you get over the large hexadecimal numbers, it isn’t much different than using IPv4. In this post, Networking Consultant Sean Wilkins shows how IPv6 addresses and subnetting work the same as with IPv4 address when converted to binary.

Since the IPv4 address space will soon be replaced, now is a great time to familiarize yourselves with IPv6. In this post, Sean Wilkins discusses the differences between the IPv6 header and the IPv4 header.

This article by Networking Consultant Sean Wilkins takes a look at some of the most common problems that are seen when redistributing to and from Cisco’s Enhanced Interior Gateway Routing Protocol (EIGRP).

Are you looking to gain experience with the Cisco Unified Computing System (UCS) platform, but don’t have access to a UCS lab? No problem! Sean Wilkins shows you how to use UCS Platform Emulator (UCSPE), Cisco’s perfect low cost solution.

Sean Wilkins explains how to implement a first-hop redundancy protocol, using Cisco’s Hot Standby Router Protocol (HSRP), Virtual Router Redundancy Protocol (VRRP), and Gateway Load Balancing Protocol (GLBP). This article gives an overview of these protocols and describes how they differ.

Networking Consultant Sean Wilkins takes a look at the Enhanced Interior Gateway Routing Protocol (EIGRP), how its metric is calculated, and how this information can be used to ensure that traffic is taking the path that is expected.
