Estimate EVPN route-type counts and control-plane memory from VTEPs, MAC addresses, VNIs and prefixes.
Every VTEP advertises each locally learned MAC, and again with its IP when ARP or ND suppression is enabled, so type-2 routes dominate the table. Type-3 routes scale with VNIs per VTEP, and type-5 carries routed prefixes between VRFs. EVPN fabrics fail at the control plane long before the data plane, and this is the figure to compare against the platform's documented MAC, ARP and BGP path limits.
EVPN Route
type-2 = VTEPs × MACs × 2 (MAC and MAC/IP), type-3 = VTEPs × VNIs, type-5 = advertised prefixes; total is their sum.

This calculator takes 5 inputs: VTEPs in the fabric, MAC addresses learned per VTEP, VNIs active per VTEP, IP prefixes advertised (type 5), Control-plane memory per route. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
