#EXTREME-1
configure vlan Default delete ports all
configure vr vr-Default delete ports 1-48

create vr vr-VXLAN

create vlan vxlan-tranzit vr vr-VXLAN
configure vlan vxlan-tranzit tag 850
configure vlan vxlan-tranzit ipaddress 123.123.123.1/30
configure vlan vxlan-tranzit add ports 48 tagged

create vlan vxlan-test vr vr-VXLAN
configure vlan vxlan-test tag 860
configure vlan vxlan-test add ports 1 untagged

configure virtual-network local-endpoint ipaddress 123.123.123.1 vr "vr-VXLAN"
create virtual-network "vnet" flooding standard
configure virtual-network "vnet" vxlan vni 10
configure virtual-network "vnet" add vlan vxlan-test
create virtual-network remote-endpoint vxlan ipaddress 123.123.123.2 vr vr-VXLAN
configure virtual-network vnet add remote-endpoint vxlan ipaddress 123.123.123.2 vr vr-VXLAN
 

#EXTREME-2

In virtualXOS VxLAN not working

I was also attempting to lab out a similar situation, I’ve also run into the same problem.

It seems the vxlan UDP packets are sent to the destination, however I never see them on the VLAN on the other side.
