Hi @MHM Cisco World thanks for that, and my apologies for the delay in getting back to you.
MAC address F839182A0D0D is the MAC address of the switch physical interface on the "client" switch connected to leaf 1 (.3). See below:
LEAF1_CLIENT#sh int g1/0/13
GigabitEthernet1/0/13 is up, line protocol is up (connected)
Hardware is Gigabit Ethernet, address is f839.182a.0d0d (bia f839.182a.0d0d)
LEAF1_CLIENT#sh run int g1/0/13
interface GigabitEthernet1/0/13
description TO_LEAF19500X
switchport trunk allowed vlan 100-103
switchport mode trunk
end
As instructed, I have changed the topology, so each "Client" switch is configured so that its uplink is in non-switchport mode and has an IP address configured on the physical interface connecting to the leaf switches. Example of the configuration for each "Client" below:
LEAF1_CLIENT(config-if)#do sh run int g1/0/13
interface GigabitEthernet1/0/13
description TO_LEAF19500X
no switchport
ip address 192.168.100.103 255.255.255.0
end
With this configuration the error appeared once when new NVE peers were brought up / added but after that there were no more errors.
I then moved each LEAF switch interface connecting to the "clients" back to a trunk port but left the "client" switches in no-switchport mode. This obviously broke the client connectivity as the VLAN tagging did not align but the nve peering came up and, again, the error appeared once and then stopped.
Next, I moved the "client" switch interfaces back to trunk mode adding one VLAN at a time and one "client" switch at a time but without any IP addressing on the "clients". The error did not re-appear.
At this point LEAF1 (.3) was once again advertising the physical interface MAC:

Note: At this point, without any IP addressing on the VLAN interfaces on the "client" switch, there is no MAC addresses for the individual VLANs (no SVIs).
I then added an SVI to the "client" switch attached to LEAF1 (.3) for the VLAN 100 interface. The error has once again started again on all LEAF switches.
So, the error only happens when SVI interfaces are created on the "client" switches which is when each VLAN/SVI has a MAC address associated with it. It also happens even when only one "client" switch has an SVI for a single VLAN.
Lastly, I tried removing the IP address off the SVI (but still having the SVI / VLAN Interface). This resulted in no errors but also no MAC associated when looking at:
LEAF1-9500-16X_VTEP#show l2route evpn mac ip topology 10100

I'm not sure what to make of that. Any ideas?
I have attached all the same output as previous for your review - this is at the point where there was no trunk configured between "client" switch and LEAF and the interface was configured on the "client" switch as "no switchport".
