Nexus - minimal required features to support VXLAN

[dukenuk96]

Let's assume that I want to build VXLAN fabric from scratch based on Nexus 9000 switches in standalone (NX-OS) mode with IS-IS underlay. The question is - what minimal required features to support VXLAN I must enable on spines and leafs?

Things that I have found are:

# spines
!
!
feature bgp
feature pim
feature isis
feature bfd
// ??? nv overlay evpn ??? ///
!
!
!
# leafs
!
!
feature nv overlay
feature vn-segment-vlan-based
feature bgp
nv overlay evpn
feature pim
feature isis
feature interface-vlan
feature bfd
!
!
!

So I am not sure that I should enable 'nv overlay evpn' on spines - since they are going to be just route reflectors. Should I add anything else?

The feature nv overlay evpn is to run the control plane for EVPN and pretty sure it will need to run on all nodes taking part in vxlan regardless of them being a leaf or spine

Are you trying to Configure VXLAN or MP-BGP EVPN?

VXLAN

feature ospf
feature pim
feature vn-segment-vlan-based
feature nv overlay

EVPN:

nv overlay evpn

feature bgp
feature isis
feature fabric forwarding
feature interface-vlan
feature vn-segment-vlan-based
feature nv overlay
