Overview of Packet Forwarding by Russ White
This course dives deep into how packets actually move through a network, with a practical focus on forwarding engines, routing logic, and real-world behaviors. Taught by Russ White, it’s designed to bridge the gap between protocol theory and real forwarding behavior inside routers and switches.
What You’ll Learn
Packet Forwarding Fundamentals
Understand the full path of a packet — from ingress to egress — and how decisions are made in forwarding engines.
Single vs. Multiple Forwarding Engine Architectures
Learn the differences between systems with a single forwarding engine and distributed platforms with multiple FEs and how that impacts performance and behavior.
Forwarding Engine Internals
Get introduced to FIBs, hardware/software paths, and what actually happens when a packet hits a router.
Routing Table, Forwarding Table, Redistribution & Leaking
See how the routing table (RIB) feeds into the forwarding table (FIB), and how redistribution and route leaking affect both — including unexpected behaviors in complex environments.
NAT and Packet Filtering
Explore how Network Address Translation and filtering rules (ACLs, firewalls) interact with the forwarding process where they happen in the pipeline and how they affect reachability and security.
Who Should Take This Course?
This course is ideal for:
Network engineers seeking real-world understanding of packet handling
CCNP/CCIE-level learners wanting to master the data plane
Anyone involved in design, troubleshooting, or operations of large-scale networks
By the end of the course, you'll have a clear mental model of how packets are processed not just according to RFCs, but how they behave in real, complex systems.
Taught by Russ White, this course builds your ability to design and troubleshoot networks with confidence.
