3. BGP Routing

BGP stitches the internet together. Inside enterprises and service providers, it decides paths, shapes policy, and keeps reachability stable across autonomous systems.

Why It's Important

Because one bad route can ripple everywhere. BGP lets you choose clean paths, guard borders, and survive churn without a meltdown.

How to Improve BGP Routing Skills

1. Filter ruthlessly: Prefix lists, AS-PATH filters, and communities. Advertise only what you mean. Accept only what you trust.

2. Aggregate where possible: Summarize to trim tables and lighten CPU and memory.

3. Validate origins: Deploy RPKI origin validation and maintain ROAs; monitor invalids like a hawk.

4. Stabilize sessions: Configure graceful restart, BFD for fast failure detection, and sensible timers.

5. Protect sessions: Use TTL security (GTSM) and strong authentication (MD5 or TCP-AO where supported).

6. Enforce limits: Max-prefix on neighbors, damp flapping carefully, and log route churn.

7. Design for traffic goals: Communities for steering, local-pref for policy, and MED with intent. Multipath when it fits.

8. Observe continuously: Track path changes, withdrawals, and latency impact. Build alerts for leaks and hijacks.

4. MPLS Networking

MPLS moves packets with labels, not long lookups. It’s the backbone method for VPN services, deterministic paths, and fast reroute in provider and large enterprise networks.

Why It's Important

It delivers predictable paths, strict QoS, and swift failover. That’s how voice stays crisp and critical traffic beats congestion.

How to Improve MPLS Networking Skills

1. Engineer traffic: Use RSVP-TE or Segment Routing with explicit constraints. Shape latency and jitter, don’t just hope.

2. Tune QoS: Classify at the edge, honor markings, and verify per-class guarantees across the MPLS core.

3. Enable fast reroute: FRR for sub-second failover; validate protection paths in drills.

4. Operate VPNs cleanly: Maintain RT/RD hygiene, leak routes intentionally, and document service chains.

5. Use OAM tools: LSP ping/traceroute, BFD, and performance measurement to catch silent failures.

6. Secure the core: Control LDP/IGP adjacencies, limit TTL propagation as needed, and restrict management planes.

7. Automate changes: Model LSPs and policies; push via templates to avoid drift and typos.

8. Capacity plan: Watch link utilization, track growth, and right-size headroom ahead of demand.

5. SNMP Monitoring

SNMP collects metrics and state from routers, switches, firewalls, servers—the lot. With it, you chart health, trigger alerts, and spot trouble before users do.

Why It's Important

Real-time visibility keeps outages short and surprises rare. SNMP is the bedrock of many monitoring stacks and still gets the job done.

How to Improve SNMP Monitoring Skills

1. Standardize on SNMPv3: Authentication and encryption on by default. Retire v1/v2c in production.

2. Poll with purpose: Pick the right MIBs for each device class; avoid noisy, low-value OIDs.

3. Tune alerts: Thresholds with hysteresis, deduplication, and escalation trees. Alert fatigue is real.

4. Use traps and informs: Event-driven signals for immediacy, with polling as the safety net.

5. Baseline performance: Know normal by hour and day. Anomalies pop out when you have context.

6. Segment monitoring: Group by site, role, and criticality. Set maintenance windows to quiet expected noise.

7. Secure and scale: Rate-limit, isolate pollers, and size databases for long retention and fast queries.

8. Augment with telemetry: Where supported, add streaming telemetry (gNMI, model-driven) for higher-resolution insight.

7. Wireshark Analysis

Wireshark lets you see on-the-wire truth. Packets don’t lie; they tell you where latency hides, where handshakes fail, and which device is misbehaving.

Why It's Important

When counters are vague, packets give clarity. It’s the microscope for protocol quirks and intermittent ghosts.

How to Improve Wireshark Analysis Skills

1. Master filters: Display and capture filters that slice straight to the flow you need.

2. Build profiles: Coloring rules, columns, and hotkeys tailored for TCP, TLS, DNS, or VoIP deep dives.

3. Trace conversations: Follow TCP streams, check retransmissions, windowing, and handshake timings.

4. Graph it: Use I/O graphs and flow diagrams to visualize spikes, loss, and jitter.

5. Capture cleanly: Use ring buffers, disable name resolution during capture, and mirror the right VLANs.

6. Decrypt when allowed: With proper keys, analyze TLS to confirm ciphers and app behavior.

7. Practice with real cases: Build a library of sanitized pcaps—DNS failures, MTU issues, SYN floods—to sharpen instincts.
