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…...

In this blog, we will setup a Checkpoint lab using virtualbox and gns3 on windows. Introduction In this lab we implement a basic security architecture to demonstrate the operation of a firewall cluster to protect our network. Our “security domain” is segmented into four zones: Security topology Our security topology is compound by two security…
In this blog, let’s study static routing with an intermediate address to resolve in a Checkpoint firewall. Introduction Static routing is supported by CKP (Checkpoint firewalls or gateways). Let’s recall that a static route defines a destination subnet or network and the way to reach it: the outgoing interface on the gateway, a connected nexthop…
In this post, we explore the operation of Cisco FabricPath (FP) and more specifically Vlan information propagation in this fabric in comparison with other platforms: Catalyst for example from the same vendor. Introduction The case is to learn how the switches that are part of the LAN network learn about and support Vlan operation: is…...

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…
In this post, let’s understand hard drive operation and try to find a methodology (procedure) to troubleshoot it (and heal it if needed). Lab setup Let’s describe in detail our “simple” setup. for the purpose of our test we mount this setup: PC + USB to SATA adapter + Seagate 1T HDD. The most basic…
