I've tried to configure 2 VLANs on one physical interface ens33
. And ens34
is used to access the internet But I can't ping VM from other hosts. The VM network adapter is in 192.168.100.0/22 network.
The /etc/netplan/00-installer-config.yaml
:
ethernets:
ens33:
dhcp4: true
ens34:
dhcp4: true
version: 2
vlans:
ens33.100:
id: 100
link: ens33
addresses:
- 192.168.100.70/24
ens33.101:
id: 101
link: ens33
addresses:
- 192.168.101.70/24
The ip addr
:

The 802.1q is supported:
root@gateway:~# lsmod | grep 8021q
8021q 36864 0
garp 20480 1 8021q
mrp 20480 1 8021q
And traffic between two VMs is untagged, host 192.168.100.70 don't reply on ARP messages. Traffic
Could you help me to find out the problem, please?
