Vlanif vs Sub-interface

Hi all!

My questions are as follows:

Both VLANIF interfaces and sub-interfaces can terminate Layer 2 packets and forward Layer 3 packets. If Layer 2 packets do not need to traverse the device, what is the choice of the two types of configurations? In which situations it’s better to use the VLANIF interface? And what is the advantage of the Layer 3 sub-interface?

Can you help me? Thanks!

Hi Steelbule,

It's recommended to use the Layer 2 interface(VLANIF interface) when VRRP heartbeat packets need to be transmitted between two devices.

In other scenarios, you are advised to use sub-interfaces.

If only the sub-interface is used, the device maintains the ARP table. If a VLANIF interface is configured, the device also needs to maintain the MAC address table.

If you have any problems, please post them in our Community. We are happy to solve them for you!
