Four necessary steps in routing fast convergence
When it comes to fast convergence, first thing that we need to understand what is convergence?
Best Practices in Network Design
Be careful when you use STP and HSRP together!
In the networks, we don’t have only single protocol. There are always many protocols and their interaction/synchronization is important. Otherwise, blackholes, routing or switching loops can occur or at least suboptimal routing/forwarding can be a problem.
Fast Convergence and Network Stability Considerations in Service Provider Network
Service Provider Network design and deployment is one of the most mysterious parts of Networking. Usually we don’t see real life SP network design and deployment discussions.
Ask these questions before you replace any technology in your network !
If you are replacing one technology with the other, these questions you should be asking. This may not be the complete list and one is maybe more important than the other for your network , but definitely keep in mind or come back to this post and check before you replace one technology with another …

Flat/Single Area OSPF network is not a problem!
Flat OSPF network, or single area OSPF networks are real. In fact most of the OSPF network today deployed, is flat OSPF networks. But how many routers can be placed safely in an OSPF area ? Any number from the real world OSPF deployment ? I will share in this post.
Interdatacenter broadcast control – ARP Proxy in OTV and EVPN
Arp Proxy – When it comes to multi domain or Inter datacenter communication, minimizing the broadcast traffic between the datacenters is an important scaling requirement. Especially if you are dealing with millions of end hosts, localizing the broadcast traffic is critical to save resources on the network and the end hosts. Resources are bandwidth , …

MPLS Layer 3 VPN Deployment
In this post I will explain MPLS Layer 3 VPN deployment by providing a case study. This deployment mainly will be for green field environment where you deploy network nodes and protocols from scratch. This post doesn’t cover migration from Legacy transport mechanisms such as ATM and Frame Relay migration as it is covered in …
Design considerations for network mergers and acquisitions
Network mergers and acquisitions are the processes which can be seen in any type of businesses. As a network designers, our job to identify the business requirements of both existing networks and the merged network and finding best possible technical solutions for the business.
What is reliability in networking?
What is reliability in networking ? Why reliability is an important design tool ? I will provide the answers of these questions with the examples in this post.
