Network Troubleshooting Tip – Model Driven

No matter what the specific role, as an IT professional, you are going to be tasked to solve problems. Whether you are in a direct support role, part of an escalation team, or on the architecture/engineering team, you are potentially seen as someone who “fixes all the things”. Sometimes though, I think it can beContinue reading “Network Troubleshooting Tip – Model Driven”

OSPF Route Optimization – Route Summarization (Post 4)

You’ve made it to the 4th and final post in the OSPF Route Optimization series, I’m proud of you! I honestly wasn’t sure if I’d make it this far, myself. Anyway, in this post we will build upon the work we accomplished in post 3, in which we converted our flat, single area OSPF topologyContinue reading “OSPF Route Optimization – Route Summarization (Post 4)”

OSPF Route Optimization – Multi-Area OSPF (Post 3)

In this post of the OSPF Route Optimization series, we take a look at multi-area OSPF. As stated before, while single-area OSPF provides us with global IP reachability, it tends to not scale well from an efficiency standpoint as the network grows. In our sample topology, we will treat the “inside” zone of each siteContinue reading “OSPF Route Optimization – Multi-Area OSPF (Post 3)”

OSPF Route Optimization – Single Area OSPF (Post 2)

In this second post of the OSPF Route Optimization series, we take a look at our sample topology network configured with a single OSPF area. We will see that while we have global IP reachability throughout the network, the routing tables are not very efficient, and this design may not scale well. Here is anotherContinue reading “OSPF Route Optimization – Single Area OSPF (Post 2)”

OSPF Route Optimization – Background (Post 1)

When it comes to global reachability within an organization, dynamic routing is a beautiful thing. There are multiple internal gateway protocols (IGPs) out there, but in this series of posts, we are going to focus on OSPF. Taking this focus a step further, we will go through IP/subnet design and routing table optimization. As withContinue reading “OSPF Route Optimization – Background (Post 1)”
