Hi,
Testing vxlan on VyOS 1.4 and found issue, wrong remote VTEP ip address!

##leaf-1
set interfaces dummy dum0 address '192.168.10.1/32'
set interfaces vxlan vxlan10100 source-address '192.168.10.1'

This VyOS Platform Blog with same issues.
source-address '172.29.0.1' but show evpn mac vni shows wrong address!
As a result, it is not possible to use ECMP!

##leaf-1
set interfaces dummy dum0 address '192.168.10.1/32'
set interfaces vxlan vxlan10100 source-address '192.168.10.1'
set protocols bgp parameters router-id 192.168.10.1

##leaf-6
set interfaces dummy dum0 address '192.168.10.6/32'
set interfaces vxlan vxlan10100 source-address '192.168.10.6'
set protocols bgp parameters router-id 192.168.10.6

and now the output of the command show evpn mac vni looks much better

vyos@leaf-1:~$ show evpn mac vni all
