1. Cisco IOS
Cisco IOS (Internetwork Operating System) runs on most Cisco routers and switches and provides the command-line interface, management controls, routing, switching, and security features that make Cisco networks tick.
Why It's Important
IOS is the backbone for Cisco devices. It’s where policy becomes packets—reliable operations, secure access, and consistent configuration, all in one place.
How to Improve Cisco IOS Skills
Make it faster, safer, calmer under pressure:
Update on a schedule: Track recommended releases and patch known issues promptly.
Harden configs: Lock down management planes, disable unused services, enforce AAA, and encrypt in-flight control traffic.
Prioritize traffic: Build QoS policies for real business flows. Shape, police, and queue with intent.
Standardize templates: Golden configs, baseline banners, consistent logging and NTP. Version-control them.
Measure everything: NetFlow/IPFIX, SNMP, telemetry. Alarms that wake you only when it matters.
Layered security: ACLs, zone-based firewall, VPN where appropriate, and strict device access policies.
Practice: Lab changes, test rollbacks, and document quirks per platform.
Small disciplines compound—your network gets quieter, safer, easier to run.

3. BGP (Border Gateway Protocol)
BGP moves reachability between autonomous systems, picks paths, and keeps the internet stitched together. It’s policy more than protocol—your choices shape your routes.
Why It's Important
Without BGP, there’s no scalable interdomain routing. For enterprises and service providers, it’s how external connectivity, multi-homing, and intersite policies actually happen.
How to Improve BGP (Border Gateway Protocol) Skills
Filter ruthlessly: Inbound and outbound. Stop leaks. Deny bogons. Only announce what you own.
Aggregate: Summarize where possible to shrink tables and steady convergence.
Design with reflectors: Route reflectors or confederations tame iBGP sprawl in larger topologies.
Protect sessions: TCP MD5/AEAD where supported, TTL security, and dampen flaps. MaxPrefix on both sides.
RPKI first: Publish ROAs, validate origins, and adopt policy to drop invalids. Monitor coverage.
Use communities: Tag routes for selective export, prepends, local-pref tweaks, and traffic engineering.
Telemetry and alerting: Watch adjacencies, churn, path changes, and prefix counts. Detect anomalies fast.
Peering hygiene: Clear policies, documented IRR entries, and periodic audits with peers.
Capacity discipline: Track FIB/RIB size, memory, and CPU headroom; plan upgrades before the wall.
Practice incidents: Simulate leaks, hijacks, and path withdrawals. Drill your response.
BGP rewards caution and clarity. Messy policy equals messy days.

4. MPLS (Multiprotocol Label Switching)
MPLS forwards by labels, not long lookups. That means tighter traffic engineering, VPN separation, and predictable paths through complex backbones.
Why It's Important
It delivers QoS and isolation at scale. Mission-critical apps get the treatment they deserve; networks stay orderly under load.
How to Improve MPLS (Multiprotocol Label Switching) Skills
Plan headroom: Track traffic by class. Reserve buffers. Avoid stealth congestion.
QoS end-to-end: Consistent marking, queues, and drops across the entire LSP path.
Redundancy that reacts: Bidirectional Forwarding Detection (BFD) and fast reroute to keep sessions alive through failures.
Traffic Engineering: Steer LSPs with constraints. Balance links, protect primaries.
Harden control planes: Rate-limit LDP/RSVP, protect labels, and audit neighbors.
Instrument the core: Per-class performance monitoring, LSP ping/trace, and synthetic probes.
Upskill the team: Shared mental models—label stack behavior, penultimate hop popping, VPNv4/v6 nuances.
Engineered paths beat wishful thinking.

5. IPv6
IPv6 brings a vast address space, streamlined autoconfiguration, and improvements that modernize routing and security posture. The world ran out of IPv4; growth rides on v6.
Why It's Important
Address abundance, cleaner subnetting, and end-to-end reachability. Fewer NAT headaches. More sustainable network design.
How to Improve IPv6 Skills
Have a plan: Dual-stack where feasible, staged rollouts, and defined cutovers. Document addressing, DNS, and routing policies.
Train the team: Neighbor discovery, SLAAC vs. DHCPv6, privacy extensions, RA guard, and ICMPv6 essentials.
Verify gear: Hardware, firmware, security tools—confirm feature parity and performance on IPv6.
Security specifics: RA guard, DHCPv6 guard, uRPF, first-hop security, and proper ICMPv6 handling (don’t break PMTUD).
Monitor with v6 in mind: Flow records, logs, and dashboards that understand IPv6 fields and volume.
Work with providers: Native v6 transit, tested tunnels only when necessary, and public-facing services enabled with AAAA and DNSSEC where applicable.
Don’t bolt IPv6 on—design it like you mean it.

6. VMware NSX
NSX virtualizes networking and security—logical switches, routers, firewalls, and overlays as software, not boxes. Micro-segmentation without rack rewiring.
Why It's Important
Security follows workloads, automation becomes natural, and network changes move at cloud speed.
How to Improve VMware NSX Skills
Standardize on NSX‑T: Align on the current release train; use the migration coordinator if you’re coming from NSX‑V.
Design for intent: Clear tier-0/tier-1 roles, route redistribution rules, and overlay/underlay boundaries.
Micro-segmentation that matters: Start with high-value app tiers. Tight rules, minimal any-any, measurable blast radius cuts.
Automate APIs: Use NSX REST APIs and infrastructure-as-code for repeatable deployments and policy governance.
Performance tuning: Right-size edge nodes, optimize uplinks, and verify MTU end-to-end for overlays.
Security integration: Tie in workload protection tools for detection and response; keep signatures and policies fresh.
Virtual networks move fast—document guardrails, then let automation do the heavy lifting.

8. SolarWinds
SolarWinds provides monitoring, configuration management, and observability for networks and systems. Dashboards to see, alerts to act, automation for the grind.
Why It's Important
When visibility is missing, downtime lingers. A well-tuned platform shortens mean time to detect and fix.
How to Improve SolarWinds Skills
Patch quickly: Keep the platform current—features improve, risks shrink.
Harden the stack: Least privilege, network segmentation for the server, MFA, and strict API credentials. Assume the platform is high value and protect it that way.
Tight discovery: Curate device roles, custom properties, and polling intervals. Fewer false alarms, better signal.
Automate configs: Scheduled backups, compliance checks, and drift detection for network devices.
