Preparing a validation for PR https://github.com/vyos/vyos-1x/pull/650 I noticed the following:
Given the following topology:
{F1116235}
R1 uses a VLAN1 interface to to SW1, which uses the port as "trunk" interface. The switch used is an Arista vEOS-LAB device.
```
vyos@R1# show interfaces
ethernet eth0 {
vif 1 {
address 192.0.2.1/24
}
}
```
```
vyos@R2# show interfaces ethernet
ethernet eth1 {
address 192.0.2.10/24
hw-id 50:00:00:04:00:01
}
```
The devices can not ping each other. As soon as I move the address on R1 from VIF1 to the interface itself, traffic starts to flow. Is this expected? If so, why support a VIF of 1?
