When RIP Advertises Dynamically Learnt Routes
This post is a part of series of posts about RIP dynamic routing protocol. Here we deepen our understanding on how RIP protocol advertises learnt RIP routes. A simple case is where a route is in the middle of this update process dans got a better route than RIP. Introduction Let’s recall first that RIP...
vPC Versus VSS Technology
Dans ce blog, nous discutons vPV et VSS. Introduction Si l’objectif “historique” est le même : s’affranchir de la limitation de STP (blocage de ports pour prévenir les boucles), de l’usage des FHRP (HSRP, VRRP) pour équilibrer les liens, d’augmenter les performances en débit et capacité de calcul, d’éliminer les SPOF liés à l’utilisation d’un...
Travailler Son CV
Le CV est une étape importante de toute recherche d’emploi, au moins pour initier le processus (répondre à une offre, candidature spontanée, etc.)… plus encore, c’est une occasion de se poser, de réfléchir son développement, son expérience et de se projeter dans une nouvelle opportunité! Une approche classique du CV Pour nombre de “demandeurs d’emploi”,...
Let’s Find Out About (Static) MPLS… From The Start!
In this post, we’ll discuss the motivation and a basic operation of an MPLS network. In the first part, we’ll introduce this protocol and our setup (using GNS3) that put it into play. We’ll try next, to explore the functionnality of this protocol using a very simple and basic example using both Cisco and HPE...
ML-Optimized Beam-Based Radio Coverage Processing in IEEE 802.11 Wlan Networks
In this post, we present the work fully available under this link: ML-Optimized Beam-based Radio Coverage Processing in IEEE 802.11 WLAN Networks, about radio coverage processing in wlan and its optimization using machine learning (ML). Why dynamic RRM is important Dynamic Radio Resource Management (RRM) is a major building block of Wireless LAN Controllers (WLC)...

Multicast Routing: Hold ASM For A Moment, Let’s Do SSM!… Part 4/6

dexterd7 months ago3 months ago06 mins

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…...

RIP Time(r)s, Let’s Understand The Flush Operation

dexterd7 months ago3 months ago16 mins

RIP is Routing Information Protocol, one of the IGP or Interior Gateway Porotocols called also a vector-based routing protocol in contrast with link-state, hybrid or path-based protocols. The function of this protocol is very simple, send updates about known networks through local interfaces enabled for this sending… In this lab we use a standard version…

Multicast Routing: Rather Than Dense, Sparse It And Let’s Meet At Rendez-Vous Point… Part 5/6

dexterd8 months ago3 months ago05 mins

In this post let’s detail the operation of PIM (Protocol Independent Multicast) in sparse mode. Previous posts tackled the operation of PIM dense mode. Let’s recall that PIM is the multicast routing protocol that allows PIM routers exchange information needed distribute multicast traffic to receivers. Introduction This blog is a part of a serie of…...

At the Begining, … It Was not DMVPN!

dexterd8 months ago3 months ago06 mins

In this blog, let’s discover the DMVPN feature. DMVPN stands for dynamic multipoint virtual private network and as per its naming, refers to the ability for many routers to share the same network built on a Wan equivalent to being connected to the same Lan. Before we start Before we start a little refresh on…

WAFing… A Grasp Of Web Application Firewalling

luffyd7 months ago3 months ago06 mins

Introduction Dans cet article nous discutons de la fonction de base d’un WAF ou pare-feu d’applications web. Comme son nom l’indique il s’agit de sécuriser l’application, plus précisemment l’accès à cette application, et ne se préoccupe pas nécessairement d’autres aspects sécuritaires : réseau, d’autres applicatifs (niveau 7 OSI) ou de transport (niveau 4 et 5…
