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?
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
