Nexus 9K VxLAN/EVPN L3VNI on global VRF

Hi all,

​

I am trying to create a vxlan/evpn DCI in order to connect to DC's with a pair of nexus 9300 on each side.

While the cisco evpn multisite whitepaper, uses VRFs for each tenant, I only have one tenant and so I tried to use only the global VRF to deploy. But I have problems with the L3VNI, which does not go up, when in global VRF.

So, I have vlan 700/VNI 5000 and an SVI in global VRF as "ip forward" but the VNI 5000 remains in "down" state. When I do the same in VRF, it works.

The config is like:

​

vlan 700

name l3-vni

vn-segment 15000

​

interface Vlan700

no shutdown

ip forward

​

interface nve1

no shutdown

host-reachability protocol bgp

source-interface loopback1

member vni 15000 associate-vrf

member vni 15002 associate-vrf

member vni 16000

suppress-arp

ingress-replication protocol bgp

​

Interface VNI Multicast-group State Mode Type [BD/VRF] Flags

--------- -------- ----------------- ----- ---- ------------------ -----

nve1 15000 n/a Down CP L3 [--]

nve1 15002 n/a Up CP L3 [t1]

nve1 16000 UnicastBGP Up CP L2 [720] SA

​

Is this a bug or it is not supposed to work in the global VRF (which sounds strange)?
