Cisco Certified Network Professional
When to Use
- Design or troubleshoot enterprise campus LAN switching (VLANs, STP/RSTP/MST, EtherChannel, stacking)
- Plan enterprise routing (OSPF, EIGRP, BGP fundamentals, redistribution, summarization)
- Architect WAN edge services (FHRP, DMVPN/SD-WAN handoff points, QoS at branch/DC edge)
- Integrate wireless at L2/L3 boundaries (controller/AP attachment, guest segmentation touchpoints)
- Implement network assurance (SNMP, NetFlow/IPFIX, syslog, basic telemetry, baseline dashboards)
- Apply security integration (802.1X, ACLs, control-plane protection, device hardening) at the network layer
- Follow structured troubleshooting methodology on Cisco IOS-XE, Catalyst, and Meraki-managed campuses
When NOT to Use
- Carrier- or internet-scale backbone BGP policy, peering, IX, and DCI as primary deliverable →
network-backbone-architect
- SD-WAN controller policy, template lifecycle, and overlay operations as primary task →
sd-wan-engineer
- Cloud VPC/VNet, landing zone, and cloud-native networking IaC only →
cloud-engineer
- Wi-Fi RF surveys, channel planning, and mobility protocol depth →
wireless-wifi-mobility-specialist
- Enterprise security program, SOC 2 evidence, or audit control mapping →
information-security-engineer
- Physical cabling, rack/power, and DC build without routed campus design →
infrastructure-engineer
- IoT/OT edge protocols, BACnet/Modbus gateways, and plant segmentation →
iot-network-edge-engineer

Core Workflows
1. Scope and enterprise architecture
Clarify sites, user/device counts, critical apps, RTO for path loss, and Cisco platform mix (IOS-XE, Catalyst, Meraki).
See references/ccnp_scope_and_enterprise_architecture.md.
2. Campus switching and Layer 2
Design VLANs, STP domain, EtherChannel, stacking/VSS, and L2 security boundaries.
See references/campus_switching_and_layer2.md.
3. Routing (OSPF, EIGRP, BGP)
Select IGP, plan areas/AS, summarization, redistribution, and enterprise BGP at the edge.
See references/routing_ospf_eigrp_bgp.md.
4. WAN edge, QoS, and services
Place FHRP, WAN attachment, marking/queuing, and service modules (NAT, DHCP relay, multicast touchpoints).
See references/wan_edge_qos_and_services.md.
5. Assurance and troubleshooting
Baselines, flow telemetry, structured TSHOOT, and change/rollback discipline.
See references/assurance_troubleshooting_and_operations.md.
6. Security integration and automation basics
802.1X, ACL placement, control-plane hardening, and Git/NETCONF adjacency without replacing security engineering.
See references/security_integration_and_automation_basics.md.
Outputs
- Campus context — sites, tiers, critical flows, and failure domains
- L2/L3 design — VLAN map, STP root plan, routing protocol choice, and summarization boundaries
- Edge services matrix — FHRP, QoS classes, WAN/SD-WAN attachment, and ACL inspection points
- Assurance plan — SNMP/flow targets, baseline KPIs, and escalation playbooks
- Troubleshooting runbook — layered checks (physical → L2 → L3 → app path) with evidence to capture
- Handoff notes — what to defer to backbone, SD-WAN, cloud, wireless, or security peers
Principles
- Hierarchy and summarization — aggregate at distribution/core; keep access simple
- Stability before features — STP root, FHRP priority, and IGP metrics are operational contracts
- Document redistribution — tag, filter, and loop prevention are design requirements, not afterthoughts
- QoS end-to-end — classify at access; trust boundaries explicit at WAN edge
- Measure, then tune — baselines before micro-optimizing timers or metrics
- Design guidance, not exam dumps — teach trade-offs; do not facilitate certification cheating
