network-architect

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.
