About This Architecture

Multi-site IPWAN network with dual hub redundancy, connecting metro, regional, and remote sites through MPLS primary paths and internet VPN fallback. Hub 1 and Hub 2 core routers with firewalls provide active-passive redundancy across the WAN backbone, while metro sites connect via dark fibre E-lines and regional sites use MPLS or internet uplinks. Remote and APY sites leverage 4G secure APN gateways with internet VPN backup for branch connectivity. This architecture demonstrates enterprise-grade WAN resilience, traffic engineering, and multi-tier site classification for organizations requiring high availability across geographically dispersed locations. Fork this diagram on Diagrams.so to customize hub failover policies, add site-specific QoS rules, or adapt the topology for your regional network design. The active-passive hub redundancy pattern minimizes failover complexity while the layered distribution approach scales efficiently from core to remote access points.
