The Arista 7800R3 Series FlexRoute engine provides the flexible scalability to support deployment as a routing platform with Internet scale routing. All Arista 7800R3 Series support FlexRoute engines providing the scalability to support deployment as a routing platform with Internet scale. The 7800R3 Series Accelerated sFlow feature samples and processes flow samples at line rate.
The 7800R3K Series support a series of flexible profiles that leverage common resources for different network roles including up to 5M IP routes. Algorithmic ACLs enable more flexible and scalable solutions for access control, policy based forwarding and network telemetry, available on the Arista 7800R3, 7800R3A, 7800R3K and 7800R3AK series.
