Did some quick experiments on my WRT1900ACv1 (Mamba) now that DSA is
finally in master...
I wonder if I have understood this correctly:
1) vlan_filtering is required when bridging tagged and untagged DSA
ports, and
2) all bridge ports, including the wireless VIFs, must be configured
with the correct VIDs when vlan_filtering is enabled
An if so, how are we supposed to configure that?
I guess a real example helps illustrating the problem. My example
network has 3 bridges, each connecting a set of untagged ports/VIFs with
one specific tagged vlan on the "wan" port:
config interface 'lan'
option type 'bridge'
option ifname 'wan.7 lan2 lan3 lan4'
option proto 'none'
config interface 'antiboks'
option ifname 'wan.8'
option type 'bridge'
option proto 'none'
config interface 'oob'
option ifname 'wan.203 lan1'
option type 'bridge'
option proto 'static'
option ipaddr '192.168.99.2'
option netmask '255.255.255.0'
option dns '192.168.99.1'
option dns_search 'mork.no'
(I realize that this could be merged to a single bridge wth
vlan_filtering, but that doesn't really change the configuration
problem.)
For now I have just hardcoded bridge, port and VIF names in a simple
script. But this is obviously not a workable permanent solution..
# 1. enable vlan filtering on all bridges
for b in lan antiboks oob; do
echo 1 >/sys/class/net/br-$b/bridge/vlan_filtering
done
# 2. configure the vlans for each bridge port
for p in wan.7 wlan0 wlan1 lan2 lan3 lan4; do
bridge vlan add vid 7 pvid untagged dev $p
bridge vlan del vid 1 dev $p
done
for p in wan.8 wlan0-1 wlan1-1; do
bridge vlan add vid 8 pvid untagged dev $p
bridge vlan del vid 1 dev $p
done
for p in wan.203 wlan0-2 lan1; do
bridge vlan add vid 203 pvid untagged dev $p
bridge vlan del vid 1 dev $p
done
# 3. configure vlan for local bridge interfaces
bridge vlan add vid 203 pvid untagged dev br-oob self
bridge vlan del vid 1 dev br-oob self
The working result is:
