To reproduce:
```
set interfaces vxlan vxlan3000 mtu '1500'
set interfaces vxlan vxlan3000 parameters nolearning
set interfaces vxlan vxlan3000 port '4789'
set interfaces vxlan vxlan3000 source-address '172.29.255.1'
set interfaces vxlan vxlan3000 vni '3000'
set interfaces bridge br3000 address '10.2.1.1/24'
set interfaces bridge br3000 description 'customer red'
set interfaces bridge br3000 member interface eth5
set interfaces bridge br3000 member interface vxlan3000
set interfaces bridge br3000 vrf 'red'
set protocols bgp address-family l2vpn-evpn advertise ipv4 unicast
set protocols bgp address-family l2vpn-evpn advertise-all-vni
set protocols bgp system-as '65001'
set vrf name red protocols bgp address-family ipv4-unicast redistribute connected
set vrf name red protocols bgp address-family l2vpn-evpn advertise ipv4 unicast
set vrf name red protocols bgp system-as '65001'
set vrf name red table '3000'
set vrf name red vni '3000'
commit
```
Then delete either vrf protocol or interfaces and vrf:
```
###
delete vrf name red protocols bgp
commit
### Requires to commit 2 times
delete interfaces bridge
delete interfaces vxlan
delete vrf
commit
###
```
