Public bug reported:
Binary package hint: linux-image-2.6.20-15-server
- When a VLAN inferface is created from a Bridge interface, the resulting vlan
interface with IP addresses etc. configured does not work.
- example /etc/network/interfaces ...
# The loopback network interface
auto lo
iface lo inet loopback
# The Bridge first ...
auto br0
iface br0 inet manual
bridge_ports eth0 eth1
bridge_maxwait 0
bridge_portprio eth0 255
bridge_pathcost eth0 65000
bridge_stp on
# Vlans on the Bridge ...
auto vlan1
iface vlan1 inet static
vlan-raw-device br0
address 10.1.1.1
netmask 255.255.255.0
network 10.1.1.0
broadcast 10.1.1.255
gateway 10.1.1.254
auto vlan2
iface vlan2 inet static
vlan-raw-device br0
address 10.1.2.1
netmask 255.255.255.0
network 10.1.2.0
broadcast 10.1.2.255
- test with vlan interfaces directly on eth0 instead of br0 performs OK.
- issue seems to be reported also on LKML and a patch has been accepted to be
applied by David Miller : please see http://lkml.org/lkml/2007/4/12/289
- this construction is used for redundancy
