Hi, We have a simple bridge setup but the ping (and other network traffic) does not work reliably. After tracing the code, it looks like a software bug. Since bridge software is been running by thousands of people. I guess I am wrong. Anyway, here is the problem. There are 2 boxes and each one has 2 interfaces, 1 ethernet and 1 wifi. STP is enabled for the bridge to avoid the loop. So the box 1

Fixes message_age field update in config BPDUs. Also checks whether the BPDU message age has exceeded bridge max age before transmitting config BPDUs.

This is the 2.4 version which incorporates the observations from Kishore about 2.6. The existing 2.4 code set the age properly, but did not increment correctly for HZ=1000 and could send a stale (expired) configuration.

Hell everyone, I am wondering if any of you had backported bridge driver to kernel 2.4.x? Thanks! Hai -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.linux-foundation.org/pipermail/bridge/attachments/2005110= 7/b0e0c092/attachment.htm

I have noticed a change in the linux bridge implementation between 2.1.15 and 2.1.17. Specifically, I do not think BPDU's (generated from another bridge) are passed across the bridge when STP is disabled. I think this relates to the LLC handling of BPDU's directly invoking br_bpdu_rcv. In 2.6.15, the br_handle_frame function would pass a BPDU to the br_handle_frame_finish function

Hi everybody. Do you know about any way to read the TCP cwnd value (congestion window) on Linux? I have read that on Linux it is not possible to enable a socket option (to read to cwnd using the program trpt). Any way to read the cwnd would be good for me. thanks Antonio

Dear Sir, I was trying to install bridge as we are installing scps gateway in our testbed.This requires us to install the bridge. Our Linux version is 2.4.18 ~3 and we are using redhat 7.2 Please let me know which is the bridge I should install and how to configure it. Before configuring the bridge what I should check in my configuration. Thanks for your time, Sincerely Rama ===== I hear

Sorry, if this question has been answered before, but I could not find out with a brief look. How can I set the MAC address for a bridge? The MAC address given for the bridge device seems to be the one it sends network packets with if the bridge device has an IP address set. Apparently the bridge starts with a zero MAC address and when the first interface is attached to it, it takes its MAC

Hi, I have 2 servers which are connected to a gateway machine. The gateway and one server are running Linux 2.6.16.2, while the third machine is running 2.6.16.5. The two ethernet ports on the gateway which are connected to the servers are combined into a single ethernet bridge device. Ever since 2.6.16, I have noticed that I can no longer cross-mount the two servers' /home directories via

Hello, i need to write a little personal patch in the bridge code. For this patch, i need to know the original src and dst mac addresses of the packet incoming to the bridge. As i work on a brouter (some packets are bridged, some are routed based on ebtable rules), packets that are routed have their mac addresses modified by the IP stack). I put a software probe in br_input.c::br_handle_frame( ),

This changes the message_age_timer calculation to use the BPDU's max age as opposed to the local bridge's max age. This is in accordance with section 8.6.2.3.2 Step 2 of the 802.1D-1998 sprecification. With the current implementation, when running with very large bridge diameters, convergance will not always occur even if a root bridge is configured to have a longer max age. Tested

Hi Rahul, If you're certain that your problem isn't as Stephen suggested, you might want to have a look at this: --- (From http://ebtables.sourceforge.net/brnf-faq.html <http://ebtables.sourceforge.net/brnf-faq.html> ) How do I let vlan-tagged traffic go through a vlan bridge port and the other traffic through a non-vlan bridge port? Suppose eth0 and eth0.15 are ports of br0.
