1. Link state monitoring added. We discovered the following problem with the existing bridge code. The code doesn't monitor the link state of the interfaces. When using two cisco switches with two Linux bridging firewalls the following problem exists. When the Cisco switch that has the blocking (stp) Linux bridge attached dies, the Linux bridge no longer receives stp packets and changes

dear all: I try to configure a bridge in my embedded linux. I had fininshed these operations below: 1) configure kernel, select the option "802.1d bridge" 2) compile bridge-utils 3) issue these commands: ifconfig eth0 0.0.0.0 ifconfig eth1 0.0.0.0 brctl addbr vb brctl addif vb eth0 brctl addif vb eth1 ifconfig vb 192.168.110.24 up

Hi, I had successfully setup my bridge (br0) but after few minutes the br0 interface seems not working. ifconfig eth0 0.0.0.0 ifconfig eth5 0.0.0.0 brctl addbr br0 brctl addif br0 eth0 brctl addif br0 eth5 brctl stp br0 on I check on my system's /var/log/syslog file. It shows something strange messages as below: - Jan 2 10:44:22 fw01 kernel: ipt_tcpmss_target: bad length (64 bytes)

I tested a few setting (bridging as module, bridging compiled within Kernel...), but nothing matched. So I decided to install 9.1 and test again. And wow, it worked with only a few command lines:

Hi, we're running the standard linux bridge setup (redundant bridge) for 5 years now. So first of all, thanks to everyone involved for implementing the bridging feature in Linux. Now I'm trying to bridge hosts connected to VLAN'ed Cisco switches using linux bridge. I'm testing the following setup (Kernel 2.6.19, bridge-utils 1.2 on both bridges)

Hi, I am a beginner of bridge. I have a problem of using Fedora Core 2 to make a simple bridge. Here is my setup: The bridge computer is installed with Fedore Core 2 (with the SE Linux patch). As I know that kernel 2.6.5 is already support bridging by default, so I didn't recompile the kernel. Then I installed bridge-utils-0.9.6-1.i386. And no additional configuration is made. After

Hello, I've been trying to implement a bridge in place for a clustered firewall at one of our office locations. Currently we NAT two class C's internally. We decided, for performance reasons, that it would make sense to put our servers into an official DMZ. So we started this bridging project. Our goal is to have two redundant firewalls in place. There is no need for active/active.

Hi, I have a PPPoE server running on a linux box that accepts multiple PPPoE sessions from clients. I'd like to bridge each of the sessions together so that it looks like just one interface. Below is a diagram: br0 | ------------------------------- | | | | ppp0 ppp1 eth3 ppp3 I've read that anything can be bridge as long as MTU is the same.
