From multicast fundamentals to a tuned, low-latency Arista fabric.
A working study notebook for network engineers targeting high-frequency trading and low-latency roles. Learn the theory, drill it with flashcards, watch the deep dives, then prove it in hands-on Arista EOS labs built for cEOS-lab and containerlab.
Learning path
Foundations
Multicast addressing, IGMP, and why fan-out matters for market data.
Trees & PIM
Shared vs source trees, RP, SSM — the mechanics that set your latency floor.
Low-latency & HFT
Cut-through, buffering, jitter, kernel bypass, FPGA, and time sync.
Arista EOS
Platforms, MLAG, LANZ/DANZ, and the CLI you will be tested on.
Hands-on labs
Ten labs from cEOS setup to PTP, QoS and BGP-unnumbered ECMP.
Prove it
Measure p99, capture microbursts, show before/after tuning.
How to use this notebook
◉ Drill
Use Flashcards deck-by-deck. Mark known cards; the counter tracks progress per deck in this browser.
▤ Build
Work Labs in order. Lab 0 stands up the environment; later labs reuse it. Every lab has verify steps and a challenge.
▶ Watch
The Videos tab links to curated YouTube searches per topic — no dead embeds, always current.
Flashcards
Click the card to flip. Keyboard: ← → navigate, Space flip.

Tip: “Mark known” hides the card from the current run. Reset a deck to bring them back.
Hands-on Arista EOS Labs
Built for cEOS-lab + containerlab. Each lab includes config, verification, and a challenge.
Video Lessons
Curated topics. Each opens a YouTube search — always live, never a dead embed.
