The more I look at this the more Im getting convinced that something is broken with the bridge.py, but it would be handy if there is somebody else in this forum that could verify this?
It seems like its this code who will actually create the bridge in the Linux kernel:
Examining this file the following commands shows up (searching for “cmd”):
add_port:
ip link set dev {value} master {ifname}
del_port:
ip link set dev {value} nomaster
add_vlan:
bridge vlan add dev {self.ifname} vid {vlan} self
del_vlan:
bridge vlan del dev {self.ifname} vid {vlan} self
add_vlan_1:
bridge vlan add dev {self.ifname} vid 1 pvid untagged self
add_vlan?:
bridge vlan add dev {interface} vid {vlan} master
add_native-vlan?:
bridge vlan add dev {interface} vid {native_vlan_id} pvid untagged master
del_vlan?:
bridge vlan del dev {interface} vid {vlan} master
And thats it?
Not a word about vrf?
Why is the add_vlan_1 stuff going on in the “def set_vlan_filter(self, state):” function?
Looking at posts such as:
Linux: Why is ARP not answered via VLAN Bridge - Server Fault and
(Vlan-aware) Bridges on Linux – SDN Clinic
linux - What are "self" and "master" options for in "bridge vlan add"? - Unix & Linux Stack Exchange
bridge(8) — iproute2 — Debian bookworm — Debian Manpages
among others the syntax is slightly different.
As it seems that this would be the proper(?) way to do it?
# Create bridge with "enable_vlan"
ip link add br0 type bridge vlan_filtering 1
ip link set br0 up
# Add vlan
bridge vlan add dev br0 vid 100 self
bridge vlan add dev br0 vid 110 self
bridge vlan add dev br0 vid 120 self
bridge vlan add dev br0 vid 200 self
bridge vlan add dev br0 vid 210 self
bridge vlan add dev br0 vid 220 self
# Add member interface
ip link set eth1 master br0
ip link set eth2 master br0
# Delete default vlan from member interface
bridge vlan del dev eth1 vid 1
bridge vlan del dev eth2 vid 1
# Add vlan to member interface
bridge vlan add dev eth1 vid 100 pvid untagged master
bridge vlan add dev eth1 vid 110 master
bridge vlan add dev eth1 vid 120 master
bridge vlan add dev eth2 vid 200 pvid untagged master
bridge vlan add dev eth2 vid 210 master
bridge vlan add dev eth2 vid 220 master
# Show result
bridge vlan show
