This article shows how to turn on the vlan filter of the bridge under linux
Starting from linux 3.8, linux supports the opening of vlan filter on the bridge, this function can make the linux bridge close to the switching function of a real switch, and supports vlan awareness, with the SVI virtual interface, it can be on the same bridge Complete the VLAN isolation and routing process between VLANs without creating a separate network bridge for each VLAN network
Assuming that there is a bridge br0, the command to open a bridge's vlan filter is as follows:
```
ip link set br0 type bridge vlan_filtering 1
# echo 1 > /sys/class/net/br0/bridge
bridge vlan add dev veth0 vid 100 pvid untagged master
bridge vlan add dev veth1 vid 200 pvid untagged master
```
Set the SVI command as follows:
```
ip link add link br0 name br0.100 type vlan id 100
ip addr add 192.168.10.1/24 dev br0.100
ip link add link br0 name br0.200 type vlan id 200
ip addr add 192.168.11.1/24 dev br0.200
```
VM1 and VM2 Point to the default gateway:
```
ip route rep default via 192.168.10.1
ip route rep default via 192.168.11.1
```
