What is tier in the first place ? If you are dealing with Service Provider networks, you hear this term a lot. But how we define Tier 1,Tier 2 and Tier 3 Service Providers ?
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.
Is fate sharing bad thing in network design? Someone asked this question recently on my youtube channel and I want to share a post for the website followers as well.
First of all, what is fate sharing ? Below is the Wikipedia definition of fate sharing.
Do we still lose packet with fast reroute? One of my students asked me this question. And I would like to share the answer with everyone.
Couple days ago I discussed some IP Mobility solutions, including LISP (Locator Identity Separation Protocol) with the CCDE students.
Don’t expect technical topic in this post. Instead I wanted to show how was my situation before and after the CCDE – Cisco Certified Design Expert !. Enjoy
Fast Convergence and the Fast Reroute Network reliability is an important design aspect for deployability of time and loss sensitive applications. When a link, node or SRLG failure occurs in a routed network, there is inevitably a period of disruption to the delivery of traffic until the network reconverges on the new topology.
Technology prototypes tested and validated by the group are now commercially available and being...
One of my readers sent me a question along these lines…
VXLAN Network Identifier is 24 bit long, giving 16 us million separate segments. However, we have to map VNI into VLANs on most switches. How can we scale up to 16 million segments when we have run out of VLAN IDs? Can we create a separate VTEP on the same switch?
VXLAN is just an encapsulation format and does not imply any particular switch architecture. What really matters in this particular case is the implementation of the MAC forwarding table in switching ASIC.

Like Internet exchanges, the goal of an edge exchange is to provide direct interconnection and traffic exchange between provider networks, but edge exchanges move that infrastructure closer to end users. Alex walks us through how these exchanges work.
