Let’s discuss in this blog, the operation of routing using a simple network example: a home network. Introduction The person in A wants to join its colleagues in location B through the network topology described in the below figure. This person needs to go back home at the evening! Should the one way and return…...

This post is part of a series of posts about dynamic routing protocols and especially RIP. We’ll try to get a deep understanding of its operation and function as an introductory to dynamic routing logic in general. You’ll see that what we think easy may hide an incrementing complexity… A little introduction Before we start…
In this blog, we’ll explore the operation of IGP interior routing protocol EIGRP over vNET trunks (another way to say networking trunking similar to vlan trunks used in L2 network by switches to trunks multiple traffics from different vlans into the same physical link) Little introduction New IOS release 15.x introduced Easy Virtual Network (EVN)…...

In this blog, we introduce SSM way of multicasting. Introduction and definitions This post is a part of a serie of post about Multicast operation from the most basic setup to a much complicated one (scenario that include more routing and receiving options, etc.). We will explore the operation of SSM (Source Specific Multicast) in…...

In this blog, we will discuss the I-BGP synchronization with IGP feature. A little introduction By definition, the BGP synchronization rule requires that when a BGP router receives information about a network from an I-BGP neighbor, it does not use this information until a matching route : static or dynamic : learned via an IGP…...

Introduction Dynamic routing protocols exchange routing information before populating routing tables and forwarding packets. For this task, RIP (routing information protocol) put into play many machanisms and rules to guarantee that this routing information exchange is consistent: not contradictory among routers. An example of such inconsistency is to receive the same routing information on two…
