Issues in creating VLAN interface using netplan on ubuntu

I have been trying to create a vlan interface on my ubuntu VM which has one network adapter. I could see that the vlan link has been successfully created, but I don't see any traffic passing through. Could it be due the similar mac address on both the links. Here is my netplan config along with ifconfig and ip link output.

netplan yaml network: ethernets: ens160: addresses: - 172.16.1.227/24 gateway4: 172.16.1.1 nameservers: addresses: - 8.8.8.8

vlans: v.206: id: 206 link: ens160 addresses: - 172.16.206.211/24 gateway4: 172.16.206.1 macaddress: 00:00:00:00:02:06

ifconfig

Use code formatting to format the command output

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
