How KODADDY designed and deployed a dual-redundancy network with automatic failover for a national trade association’s headquarters — combining Cisco Meraki SD-WAN and TP-Link Omada across 23 devices, with full Wi-Fi 6E coverage.

The Challenge

The organization’s headquarters ran on a single internet path and a single set of network gear. If the primary line or a core device failed, the entire office — phones, file sharing, cloud apps, and Wi-Fi — went down with it. Leadership wanted an infrastructure where a failure of any single component would not take the internet or the internal network offline.

The Solution: Two Independent Paths

KODADDY designed a dual-redundancy (high-availability) architecture using two independent internet circuits and two complete equipment sets that back each other up. The analogy we gave the client: a building with one water pipe loses all water if that pipe breaks — with two pipes, a break in one still leaves the other running.

  • Path 1 — Cisco Meraki (primary/active): a Meraki MX105 firewall/SD-WAN appliance handles the main internet traffic, with cloud-based security and centralized management.
  • Path 2 — TP-Link Omada (standby/backup): an Omada ER8411 gateway provides a second internet path and powers the internal switching and Wi-Fi fabric, ready to take over instantly.

The two systems are bridged over a shared internal VLAN so they operate as one network while maintaining independent failover. Traffic is segmented with VLANs to separate the main network, a legacy network, and a dedicated management network.

Wired backbone

A stack of PoE+ core and distribution switches connects the server rack to each floor’s IDF (intermediate distribution frame), with a 10 Gbps SFP+ backbone between core switches for high throughput.

Wi-Fi 6E coverage

Wi-Fi 6E access points (2.4 / 5 / 6 GHz) were deployed per floor and zone for complete coverage, cloud-managed for centralized monitoring and channel optimization.

How Failover Works

  • Primary line fails: the Meraki appliance automatically switches to the second path through the Omada gateway. Users experience little to no interruption.
  • Backup gateway fails: the primary Meraki path is already active, so internet continues uninterrupted; internal switches and Wi-Fi keep serving the local network.
  • ISP outage: if the provider itself goes down, internet is unavailable, but the internal network (file sharing, printers, local services) keeps running.

Equipment Deployed

23 devices in total — all authorized-grade, sourced and configured by KODADDY:

  • Cisco Meraki (4): MX105 firewall / SD-WAN, MS130-8X switch, and 2× CW9176D1 Wi-Fi access points.
  • TP-Link Omada (19): ER8411 multi-WAN gateway, 9× SX3206HPP PoE++ core/distribution switches (10 GbE SFP+), and 9× EAP773 / EAP783 Wi-Fi 6E access points.

The Results

  • No single point of failure for the internet path — automatic failover between two independent WAN circuits.
  • All 23 devices online and healthy, centrally monitored across both platforms.
  • Full Wi-Fi 6E coverage across every floor, with a 10 GbE switching backbone.
  • VLAN-segmented traffic separating production, legacy, and management networks.
  • A documented upgrade path (e.g., raising remaining 1 GbE links to 10 GbE) as the organization grows.
