🔐 Routing, Switching & Firewall Protocols – The Backbone of Networking In every modern enterprise network, three pillars ensure seamless communication, stability, and security: 1️⃣ Routing Protocols (Cisco Router) They determine the best path for data to travel across. 🔐 Routing, Switching & Firewall Protocols – The Backbone of Networking In every modern enterprise network, three pillars ensure seamless communication, stability, and security: 1️⃣ Routing Protocols (Cisco Router) They determine the best path for data to travel across. The stack is connected to two Secure Firewalls 3105. The Core is doing L3 routing for four VFR's. Other VFR's are routed on the Firewall. How would you configure the connection between Core and Firewall? Currently we have a transit network (VLAN 100, 192. Routes on the Core for all. For enterprise network architects and senior infrastructure engineers, determining where Layer 3 routing logic should reside—on the core switch or the Next-Generation Firewall (NGFW)—is a foundational design decision. A misstep here can either cripple network performance with unnecessary. Do y'all prefer to setup internal firewalls, pure ACLs on switches, a mix of both with VRFs and route leaking, or a different design?. and why? ACLs on switches are a last resort to me. Generally I will list a few requirements, go over the designs and discuss the pros and cons. Each room has a FortiGate Firewall and a MikroTik or HPE core-switch. Between these two switches we ran a 10Gbit fiber.
