Hi !
We have configure 2 VLAN on a switch (one for a future private network and an
other for the DMZ).
For the moment, addresses in the both VLAN are in the same address domain.
I try to bridge them, but an interface is always entering and staying in
blocking state.
The configuration is as follow :
On the switch port 23 belongs to VLAN1 and port 20 to VLAN2.
On the linux box (debian) 2 NIC. File /etc/network/inferfaces :
auto br0
iface br0 inet static
address X.Y.Z.T
netmask 255.255.255.0
broadcast X.Y.Z.255
gateway X.Y.Z.U
bridge_ports all
When I bring up br0 interface :
Jun 27 08:41:14 pollux kernel: device eth0 entered promiscuous mode
Jun 27 08:41:14 pollux kernel: eth0: Setting promiscuous mode.
Jun 27 08:41:14 pollux last message repeated 4 times
Jun 27 08:41:14 pollux kernel: device eth1 entered promiscuous mode
Jun 27 08:41:14 pollux kernel: eth1: Setting promiscuous mode.
Jun 27 08:41:14 pollux last message repeated 4 times
Jun 27 08:41:14 pollux kernel: br0: port 2(eth1) entering listening state
Jun 27 08:41:14 pollux kernel: br0: port 1(eth0) entering listening state
Jun 27 08:41:15 pollux kernel: br0: port 2(eth1) entering blocking state
Jun 27 08:41:29 pollux kernel: br0: port 1(eth0) entering learning state
Jun 27 08:41:44 pollux kernel: br0: port 1(eth0) entering forwarding state
I don't understand why eth1 is in blocking state. Any suggestion ?
Thanks a lot.
Marc.
