Welcome, dear readers and network enthusiasts! If you’ve made it this far, it’s because you’ve already survived the theory of SRv6 (Segment Routing IPv6) in our first two articles. If you haven’t already, I recommend taking a look at them so you don’t feel as lost as a packet without a router.After all, nobody wants […]
Introduction In the increasingly interconnected landscape of modern technology, efficient and unified device management has become crucial. The evolution of the TR-069 protocol to TR-369 marks a crucial point in this journey, opening new doors for service providers and end users. In this article, we’ll explore the transition from TR-069 to TR-369 and the significant […]
In this article we will talk about the process of reconfiguring Nokia G-1425-GA routers after they have been reset. In order for them to be completely reconfigured to the state they were in before the reset, an ACS TR-069 server must be up and running, persisting its previous settings. If you don’t know what an […]
Today we’re going to explore the famous DHCP Option 43, used mainly to autoconfigure devices such as Access Points, Switches, IP Phones, CPEs, IoT devices and others through TR-069. We will also show a configuration example using the DHCP Server of a Mikrotik router, delivering parameters via DHCP Option43 and allowing autoconfiguration of services in […]
Introduction When we talk about servers today, we automatically associate them with virtualization. Gone are the days when we used bare-metal servers to run just one application. With the ease of virtualization and better use of server resources, it has become almost mandatory to use your server with some virtualization software. Currently, two big names […]
Overview: BGP FlowSpec (Border Gateway Protocol Flow Specification) is an extension of the BGP protocol used to define traffic filtering rules on routers or, more simply, to generate firewall rules on routers from a BGP announcement. Unlike conventional BGP, which routes based on IPv4/IPv6 and prefix information, BGP FlowSpec allows network administrators to specify more […]
Recently, VMware ‘s new owner made a statement that echoed throughout the community: there will be no more free VMware licenses, and the cost of new licenses has increased by 40%. This drastic change in licensing policies has led many IT professionals and companies to re-evaluate their virtualization strategies. As a result, alternative solutions are […]
Overview: BGP FlowSpec (Border Gateway Protocol Flow Specification) is an extension of the BGP protocol used to define traffic filtering rules on routers. Unlike conventional BGP, which routes based on IPv4/IPv6 and prefix information, BGP FlowSpec allows network administrators to specify more granular criteria for packet forwarding, including layer 4 information (TCP/UDP ports) and even […]
Basically, Flowspec is an extension of the BGP protocol that allows routers to apply rules such as dynamic ACLs or dynamic firewall rules to specific types of traffic. These rules can be based on a variety of criteria, including source, destination, protocol, port and so on.
In recent months, our technical team has seen an alarming increase in DDoS attacks of the Carpet bombing type, characterized by intense traffic spikes generally directed at all IP addresses belonging to the ASN. These attacks have negatively impacted network connectivity, presenting an additional challenge in evading detection by many conventional DDoS security systems. Unlike […]
