Arista 7280R4 Series 800G Routing Switch

The Arista 7280R4 Series is a purpose-built WAN and edge routing platform engineered for enterprises and service providers requiring wire-rate 800G uplink density combined with deep routing table capacity. Built on Arista's proven EOS (Extensible Operating System) software stack, the 7280R4 leverages next-generation merchant silicon to provide a combination of high-bandwidth forwarding, programmable pipeline capabilities, and the routing scale necessary to peer directly with the global internet DFZ (Default-Free Zone) or operate as a high-capacity enterprise WAN edge node. The platform supports full BGP table sizes exceeding 4 million IPv4 and IPv6 prefixes, making it suitable for multi-homed internet edge, large-scale MPLS/SR-MPLS deployments, and carrier-grade peering fabrics.

The 7280R4 Series features a fixed and modular form-factor approach optimized for top-of-rack or end-of-row placement in enterprise data centers and colocation facilities. Hardware-based segment routing (SR-MPLS and SRv6) is natively supported, enabling programmable traffic engineering across wide-area networks without reliance on legacy RSVP-TE signaling. The platform integrates Arista's Advanced Event Management (AEM) and NetDB telemetry subsystems, providing sub-second streaming telemetry for operational visibility across all routing protocols, interfaces, and hardware forwarding tables. VXLAN EVPN integration allows seamless extension of overlay fabrics from campus or data center core directly to the WAN edge.

Launched in Q2 2025, the 7280R4 Series addresses the growing demand for 800G-ready interconnect infrastructure as hyperscale traffic volumes and cloud on-ramp requirements push enterprises beyond the capacity limits of legacy 100G/400G platforms. The series is fully compatible with Arista CloudVision for centralized intent-based provisioning, change management, and network-wide telemetry aggregation. Support for YANG/OpenConfig, gNMI, gRPC, and RESTful APIs ensures seamless integration with modern network automation frameworks including Ansible, Terraform, and Python-based toolchains.

Ideal for

• Enterprise internet edge peering with full DFZ BGP table support across multiple upstream transit and peering providers
• High-capacity MPLS and SR-MPLS WAN aggregation connecting branch offices, campus sites, and data centers at 800G density
• Colocation and carrier-neutral facility interconnect requiring wire-rate Layer 3 forwarding with deep buffer management
• Cloud on-ramp aggregation routing traffic to multiple hyperscale providers (AWS, Azure, GCP) via dedicated interconnect
• Segment Routing v6 (SRv6) backbone deployments enabling programmable end-to-end traffic engineering for managed service providers
• Large-scale EVPN/VXLAN WAN gateway consolidating data center overlay fabrics with external BGP routing at 800G uplink speeds
