For Verified Maximum, 16 path ECMP is tested with 40K IPv4 and 40K IPv6. The following table lists the Cisco verified limits for Cisco Nexus 3000 Series topologies that include Layer 2 and Layer 3 feature configurations. If your scale requirements exceed either the Verified Topology or the Verified Maximum limit, please contact your Cisco representative. Based on your requirements, it may be possible to validate support for your requirement, as long as the scale capability of the hardware is not exceeded. 4
