I added a bridge1 in the dom0, created a vlan interface on the dom0, added
that to the bridge1. Then I added a second interface to the domU, assigned
it to the bridge1.
Now I have a bridge0, where I can communicate with untagged vlan packets,
and a bridge1 that allows me to communicated with the domU with tagged vlan
packets.
For all the vlan's I want to use, I have to create a bridge interface on the
dom0.
This is working.
That's only way I managed to get VLANs to work with vifs.
A few months ago, there was a thread on the subject, there is some MTU
limit in the vif code that don't allow tagged frames (that are larger
thant 1500 bytes) to go through.
Hi.
I have it also on bridges. I have 3 nics. I have bridge on each:
$XENDIR/network-bridge "$@" netdev=eth0 bridge=xenbr0 vifnum=0
$XENDIR/network-bridge "$@" netdev=eth1 bridge=xenbr1 vifnum=1
$XENDIR/network-bridge "$@" netdev=eth2 bridge=xenbr2 vifnum=2
Then I have in DomU (debian stable) configuration for vlans and
everything works fine.
#auto eth0 vlan2 vlan3 vlan4
# VLAN 1 - native management VLAN
iface eth0 inet static
address 192.168.31.254
netmask 255.255.255.0
vlan_raw_device eth0
# VLAN 2 - ADSL Modem VLAN
iface vlan2 inet static
address 192.168.1.5
netmask 255.255.255.0
vlan_raw_device eth0
# VLAN 3 - DMZ VLAN
iface vlan3 inet static
address 60.241.247.213
netmask 255.255.255.248
vlan_raw_device eth0
# VLAN 4 - IntNet VLAN
iface vlan4 inet static
address 192.168.30.254
netmask 255.255.255.0
vlan_raw_device eth0
