Hi, i have an issue with the vxlan bgp vne, for some reason i'm unable to make the state UP for the VNI.
So, i'm unable to ping to the remote host for the same vlan.
For some reason i have the mac address of the remote host, but isn't storage in the ARP Table.

The topology that i'm doing is attached.
In one site have Spine and leaf topology, and the other side it's like a leaf-spine collapsed.
Hope someone can give me a hand.-
Thank you !.

Ok, didn't notice that the command advertise l2vpn evpn was deprecated, i remove vrf from BGP, and now it's working.
I just can't understand why the state still in none...anyways, now i have conectivity between hosts from the same vlan and the outside.

Could you share the following logs:
- show run vlan 300
- show run vlan 900
- show run interface vlan 300
- show run interface vlan 900
- show nve vni
I would also look at the below :
SW_BD/VNIs of interface nve1: ================================================ |======|======|=========================|======|====|======|======== |Sw BD |Vni |State |Intf |Type|Vrf-ID|Notified |======|======|=========================|======|====|======|======== |300 |1000300|NONE |nve1 |CP |0 |No |900 |1000900|NONE |nve1 |CP |4 |No |======|======|=========================|======|====|======|======== Peers of interface nve1: ============================================ no peers
It should show NVE peers.
Question: Are your other VTEPs advertising same VNI's.
Once I look at the configuration, I will be able to respond in a better way. At this point, more information is needed.

Hi, i changed a little bit the topology, becasue i lost the topology. Anyways, i'm having the same result about the nve peers.
For some reason i see no peers in the platform, but i able to ping between servers in the same vlan. Also, i have installed the BGP to l2rib, and the tunnel ID are correct.
I attached the topology, and the commands that you request.
