Multi-site enterprise network topology integrating MikroTik CCR1009 core routers, D-Link managed switches across distributed racks, and Dahua NVR surveillance systems. Data flows from access switches through aggregation layers via D-Link DGS-1510 and DGS-1210 models to core routing infrastructure, with wireless access points managed by MikroTik CCR1009 and security cameras connected through dedicated NVR nodes. This architecture demonstrates hierarchical network design with redundancy across four facility racks (2-os, 4-os, 6-os csarnok, and Porta Rack), separating surveillance, wireless, and server traffic. Network administrators can fork this topology to customize port allocations, add failover links, or adapt rack configurations for their facility layout. The design balances cost-effectiveness with managed switching capabilities suitable for mid-market enterprise deployments.
