Knowing the OSPF Network Types and how they work with different frame relay topologies is one of those things that you should know inside out if you are attempting the CCIE lab. In this next series of articles we will be looking at the 5 OSPF network as well as how and when to use [...]

Tutorial: Troubleshooting Split Horizon Issues, Part 2

By Arden Packeer, CCIE #20716 ⋅ December 30, 2007 ⋅ One comment

In my previous article on split horizon we looked at some of the problems with running a distance vector routing protocol like RIP or EIGRP over a frame relay hub and spoke topology. In this article we will be exploring the problems that split horizon might cause in an ethernet based topology. Specifically we will be looking at redistribution issues and some of the problems secondary addresses can cause….

Tutorial: Troubleshooting Split Horizon Issues, Part 1

By Arden Packeer, CCIE #20716 ⋅ December 28, 2007 ⋅ 2 comments

I was reading through Troubleshooting IP Routing Protocols by Cisco Press and came across an example of when to disable Split Horizon on an interface. This particular example involved secondary interfaces, and RIP. After reading about it I tried to go through in my mind all the circumstances in which one might need to disable or troubleshoot split horizon. I labbed up a couple of these scenarios in Dynamips and came up with the following scenarios: Using Distance Vector Routing protocol with Hub and Spoke Frame Relay, Using Distance Vector Routing protocols with Ethernet topologies, Using a Distance Vector Routing protocol with secondary addresses and Redistribution issues with Split Horizon. It is these scenarios that we will be having a look at in the next couple of articles….

BGP Local-AS
BGP allows you to manipulate your Autonomous System (AS) number in a number of different ways including confederations, local-as, and remote-as commands. This article focuses on manipulating your AS as seen by other remote AS’s using the local-as command. We will also look at some tips and tricks using this in conjunction with BGP [...]
