Is It Sufficient RIP Split-Horizon Rule To Prevent Routing Loops?
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...
How to build an .EXE for your Py Script
In this blog, let’s see how we can build an exe file from our py (python) script. Motivation Why it is interesting to build an exe for our py script? poratability, ease of execution, etc. are some reasons why to do so. Instead of opening the IDE, loading the script, run it, an exe file...
Cognitive Directional Cost-Based Transmit Power Control in Ieee 802.11 Wlan
In this post we present the work available at this link: Cognitive directional cost-based transmit power control in IEEE 802.11 WLAN, about the how to model the radio coverage area in enterprise Wlans. IEEE 802.11 Wlan networks are challenging IEEE 802.11 Wlan networks are constantly challenged for maximum overall service performance and new mobility applications:...
What WPA suite for your secured Wifi?
In this article we will discuss the use of WPA in a secured wifi context. A little introduction WPA stands for Wifi Portected Access. By protected access, the protocol define the way by which your device will authenticate to the wifi access point to be allowed to associate with this access point and futher, access...
On-boarding Catalyst 9k to the Meraki Dashboard
Introduction The Cisco Meraki solution comes with its own set of devices but allow the integration of other devices like the Catalyst 9k L2 or L3 switches. Currently, the Meraki dashboard supports the onboarding of these family models : 9200, 9300 and 9500. Reusing an existing infrastructure of Catalyst switches is energy, time and cost...

Point-to-Point OSPF Network Operation over a LAN that Connects Multiple Routers

dexterd10 months ago5 months ago07 mins

In this blog, we’ll discuss the operation of OSPF dynamic routing protocol in a specific case where all participating routers share the same LAN Ethernet broadcast network and are configured as point-to-point OSPF network. Introduction In the first part, we present the lab setup and details the routers configuration. In the second part, we analyse…...

Static Routing… Metric?!

dexterd10 months ago5 months ago03 mins

In this post we explore the operation of static routing, epecially the use of the metric feature, in a network that already runs an IGP (RIP routing protocol). Network setup In our 3 routers RIP network, both R1 and R3 advertise 13.13.13.13/32 network into RIP domain R3 is configured to offset (to add) all network…

I-BGP Synchronization With IGP

dexterd10 months ago5 months ago16 mins

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…...
