Network Design should be simple! Simplicity is the first network design best practice that I want you to remember. If you have been in the field long enough, you have probably heard about the KISS principle.
Most fundamental network design attribute should be simplicity.
Is Inter-AS MPLS VPNs commonly deployed ? In real-life deployment which Inter-AS MPLS VPN Option is most common ? What are the use cases of Inter-AS MPLS VPNs ? This is not a theory post , I will share practical information with you.
OSPF Prefix Suppression helps to company to use 200 routers in their network without any problem. You can think that, some companies use more than 200 routers in their OSPF network, why this post is special? You will understand why in 10 minutes.
We discussed LAG (Link Aggregation Group) and the ECMP (Equal Cost Multipath) on real network deployments with the Service Provider/Telco Engineer engineers on my slack group. I thought it was good discussion so you can see what others are doing and the reasons of their deployments.
Network complexity plays a very important role during network design. Every network designer tries to find the simplest design.
Is LISP Dead? Today, there are many networking technologies which haven’t been widely deployed. And among them are Internet Multicast and IPv6 although these two protocols have many benefits .
MPLS VPN and DMVPN Design – MPLS VPN is used mostly as primary connectivity and DMVPN as a backup in the small medium business. You might see in some cases DMVPN is the only the circuit between remote offices and the datacenter/HQ, or for some applications MPLS VPN might be the primary,DMVPN for the others.
OSPF Design Discussion – In the below picture, where should you place an OSPF ABR (Area Border Router) to scale OSPF design ? Why ?
Fast Reroute , Fast Convergence , WRED and WFQ. You may think that why Orhan is putting all these mechanisms together. I will give you an analogy. Those who participate my talks., know that I love using analogies.
