Linode 的 VPC 與 VLAN

看到 Linode 的「Go Private with VLANs and VPCs」這篇,裡面特地提到了 VLAN

Can a VLAN be used as a VPC on Linode?

The short answer is again, yes, we can use a VLAN as a VPC on Linode.

在「Common Use Cases for Linode's VLAN Service」這篇 (發現是 2021 年就有的資料) 裡面開頭就有提到:

This means that two or more Linodes connected via the VLAN can see each other as if they were directly connected to the same physical Ethernet network. This network supports all the logical Ethernet features like L2 broadcast and L2 multicast.

所以看起來的確是在 Linode 的 SDN 上面支援了 VLAN。記得早期是用 Cisco 的方案 (2013 年的時候有「Linode NextGen: The Network」這篇),現在不知道是什麼架構...
