Before the Next Incident: 4 HPE-SRX Controls to Enable Now

By MH-Nh1358 posted 24 days ago
Before the Next Incident: 4 HPE-SRX Controls to Enable Now Most organizations already have more firewall capability than they actively use. In many environments, the firewall is still treated mainly as a policy enforcement point, (NGFW and IPS are table-stakes nowadays) while advanced protections that improve visibility, resilience, and prevention remain disabled or only partially deployed. For Security Practitioners, that gap matters because modern attacks do not wait for perfect conditions. Threats move through encrypted traffic, newly created infrastructure, malicious downloads, and abused DNS services, often faster than security teams can respond ...

Connecting AI: The Network Behind Every Inference

By Cherishma Potluri posted Jul 16, 2026
Introduction When people think about Artificial Intelligence (AI), they usually think about models, GPUs, and applications. They picture chatbots answering questions, copilots generating content, recommendation engines personalizing experiences, or image generators creating artwork. What often goes unnoticed is the network... Every AI interaction begins and ends with a network transaction. Before a model can generate an answer, a request must travel through access networks, service provider infrastructure, transport networks, data centers, storage systems, and compute platforms. Once the response is generated, it must make the journey back to ...

BNG Chassis Redundancy with DHCP Active Lease Query and EVPN VPWS

By Sathish Eruvala posted Jul 16, 2026
When a Broadband Network Gateway goes down, thousands of subscribers lose connectivity. Traditional BNG redundancy solutions often result in subscriber session loss, requiring DHCP reinitialization and leading to service disruption. Active Lease Query (ALQ) solves this challenge by synchronizing DHCP lease states between BNG peers in real time. When the active BNG fails, the standby BNG already has all subscribers provisioned and takes over seamlessly, with no DHCP re-establishment required. In this article, we validate ALQ-based chassis redundancy on MX480 BNGs with MPC10E TRIO-based line cards using EVPN-VPWS multihoming to demonstrate scalable and ...

Secure BGP with ASPA: Preventing and fixing route leaks

By Anton Elita posted Jul 13, 2026
BGP runs on trust, and route leaks and hijacks are what happen when that trust is misplaced. This article shows how three complementary mechanisms close the gap — BGP Roles with Only-To-Customer attribute prevent and detect leaks several hops from the source, and - if the leak already happened - RPKI Route Origin Authorization (ROA) helps validate the origin AS, and Autonomous System Provider Authorization (ASPA) confirms the full AS PATH is valley-free. Introduction Any BGP speaker can advertise a syntactically valid route for almost any prefix. Commercial relationships between autonomous systems, such as customer, provider, and peer, are supposed ...

SRX MNHA: VRRP

By Karel Hendrych posted May 28, 2026
This TechPost describes an alternative solution to the native SRX Multi Node High Availability (MNHA) Switching/Hybrid Layer 2 (L2) Virtual IP address (VIP) mechanisms using Virtual Router Redundancy Protocol (VRRP). MNHA combined with VRRP can offer more flexibility and speed up convergence in some failure scenarios. The solution addresses current limitations of the native MNHA L2 VIP mechanism compared with the traditional SRX chassis-cluster technology. The additional configuration should be seen as a worthwhile investment for the flexibility and better convergence times, albeit making the configuration slightly more complex. Introduction Firewall ...

SRv6 Static LSPs

By Ricardo Dominguez Dominguez posted May 26, 2026
There are several approaches to deploying SRv6 Traffic Engineering (TE) tunnels (LSPs), depending on the operational and automation requirements of the network. These approaches include explicitly defined (static) LSPs, dynamically computed LSPs using Constraint-Based Shortest Path First (CSPF), and centrally orchestrated paths provisioned through a WAN Controller. In this two-part technical blog series, we will take a deep dive into SRv6 TE LSP architectures and operational models, focusing on both static and dynamic path computation techniques. The series will explore how SRv6 enables flexible and scalable traffic engineering, while also highlighting the ...
