TECHNICAL SKILL

Basic Redundant Internet Connection Design

Goal: Design a dual-ISP setup with failover for a small office network.

  • Key Skills: Default route configuration, failover detection (e.g., track ping), static route metrics.

  • Challenge: Ensure automatic switch-over to backup ISP when the primary fails.

  • Level Up: Implement load balancing across ISPs using policy-based routing or dual WAN routers.

TECHNICAL SKILL

Basic Routing Lab: Static vs Dynamic Routing

Goal: Build a lab with 3 routers to compare static routes and a basic dynamic protocol (BGP or OSPF).

  • Key Skills: Route tables, route propagation, hop-by-hop design.

  • Challenge: Fail a link and observe convergence behavior.

  • Level Up: Add route summarization or authentication to dynamic protocol setup

Protocol Inspection Lab with Wireshark

Goal: Capture and analyze protocol behavior under different conditions (e.g., congestion, dropped packets).

  • Key Skills: TCP 3-way handshake, retransmission analysis, QUIC vs TCP/HTTP2 inspection.

  • Challenge: Identify application slowness due to MTU mismatch or TCP window issues.

  • Level Up: Document 5 real-world root cause scenarios based on PCAP analysis

TECHNICAL skill

High Availability Network Design with Floating IPs

Goal: Build an HA design where multiple servers or gateways share a floating (virtual) IP for failover.

  • Key Skills: VRRP (or Azure Standard Load Balancer with HA ports), heartbeat, failover detection.

  • Challenge: Test failover under interface or node failure conditions.

  • Level Up: Use cloud-native health probes and routing rules to shift traffic automatically.

BGP Path Manipulation and Traffic Engineering

Goal: Influence outbound/inbound traffic flows using BGP attributes (e.g., LOCAL_PREF, MED, AS-PATH prepending).

  • Key Skills: Traffic control, policy application, attribute ordering.

  • Challenge: Force specific exit paths for different prefixes.

  • Level Up: Monitor the impact of path changes on performance using traceroute and flow logs.
