SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Provides actionable guidance to design, harden, and troubleshoot enterprise network architectures so teams can build reliable, scalable, and secure L2/L3 infrastructures without trial-and-error configuration mistakes.

Core Features & Use Cases

  • Routing & WAN Design: OSPF area planning, BGP policy and filtering, MPLS L3VPN and SD-WAN patterns, and path-control techniques.
  • Switching & L2 Resilience: VLAN design, STP variants and hardening, EtherChannel/LACP best practices, and MAC/ARP troubleshooting patterns.
  • Operational Playbooks: IPv4/IPv6 addressing and VLSM guidance, QoS DSCP mapping and LLQ/CBWFQ rules, gateway redundancy (HSRP/VRRP/GLBP) and object tracking, and stepwise OSI-based troubleshooting checklists.
  • Use Case: Review a campus-to-datacenter topology and produce IP addressing, OSPF/BGP configuration snippets, VLAN/trunking design, redundancy recommendations, and QoS markings to meet voice/video SLAs.

Quick Start

Review this network topology and provide OSPF area design, BGP filtering and next-hop guidance, VLAN segmentation and trunking corrections, redundancy failover steps, and QoS marking recommendations to improve availability and security.

Frequently Asked Questions about network-architect

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I design an OSPF area structure and BGP filtering for a campus-to-datacenter WAN?▼

Design OSPF areas and BGP filtering by mapping topology boundaries to area types, applying next-hop manipulation, and generating route filters. This yields scalable routing policies with clear failover boundaries and redundant path control.

What is the best way to segment VLANs and harden STP in an enterprise network?▼

Segment VLANs by mapping user groups to subnets and harden STP by enabling variants like RSTP or MSTP with EtherChannel LACP. This produces resilient L2 switching topologies that prevent loops and broadcast storms.

Can I use this network architecture guidance for CCNP-level Cisco IOS and NX-OS environments?▼

Yes, this guidance targets CCNP-level engineering with a focus on Cisco IOS, IOS-XE, and NX-OS while remaining vendor-agnostic where possible. It produces applicable configuration patterns for routing, switching, and QoS.

How do I configure QoS DSCP marking and LLQ CBWFQ policies to meet voice and video SLAs?▼

Configure QoS DSCP marking by classifying voice and video traffic into LLQ and CBWFQ queues. This generates prioritization policies that guarantee bandwidth and low latency for real-time applications across the WAN.

Why does my gateway redundancy failover using HSRP VRRP or GLBP need object tracking?▼

Gateway redundancy failover using HSRP, VRRP, or GLBP needs object tracking to detect upstream link failures. This ensures traffic detours away from failed paths, maintaining network availability without manual intervention.

What are the limitations of troubleshooting MPLS L3VPN and SD-WAN without stepwise OSI checklists?▼

Troubleshooting MPLS L3VPN and SD-WAN without OSI-based checklists risks missing L2 or L3 control-plane faults. Structured operational playbooks provide systematic verification, preventing trial-and-error configuration mistakes.
