similar to: [Bridge] Bridge & it's MAC address question

I am battling an issue with use of bridging with xen. For some yet undetermined reason supposedly relating to stp, they assign a mac address of fe:ff:ff:ff:ff:ff to the bridge. Was hoping someone here may be able to elaborate on that. If I enslave a bridge to an ethernet, and than restart that network interface, should the bridge operation behave the same after the ip interface is restarted?

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

Bridge locking for /sys/class/net/br0/bridge/stp_enabled was wrong. Another bug in bridge utilities makes it such that this interface, meant it wasn't being used. The locking needs to be removed from set_stp_state(), the lock is already acquired down in br_stp_start()/br_stp_stop.

Hello all, I would like to know if it is possible to have 2 bridge instances running - one for the internal network and the other for the external network. What I need to explain is that I need the internal bridge to go though the Linux Kernel and pass its packets to the external network bridge. I am also hopeful that the internal network bridge will not need an IP address as I am hoping to

Hi, In my office I have an HP Proliant server running CentOS 7. It's a minimal install without GUI. The machine has two network interface cards, and for now it's acting as gateway/firewall, and it's running ntpd, Dnsmasq and Rsnapshot. I'd like this machine to also be a KVM virtualization host, so I installed qemu-kvm and libvirt. The interface facing the LAN is enp3s0, so I

Recently ran into a problem with the 2.6.18 kernel on Xscale arch when a br= idge, with multiple interfaces on it, is configured with a redundant loop. = All interfaces are left on forwarding and nexer switch to block when the lo= op is introduced. This was tested against a 2.6.16 kernel and the problem d= id not occur, interfaces forwared and blocked correctly. Any help would be = appreciated.

Hi, I'd like to get some feedback on a proposal to enhance virtio-net to ease configuration of a VM and that would enable live migration of passthrough network SR-IOV devices. Today we have SR-IOV network devices (VFs) that can be passed into a VM in order to enable high performance networking direct within the VM. The problem I am trying to address is that this configuration is generally

Hi, I'm using linux 2.6.21.5 and our kernel is freeze. The problem is, if I create a Software bridge using $brctl command. and add two interfaces say, eth0.0 and eth0.1 using $brctl addbr br-lan $brctl addif br-lan eth0.0 $brctl addif br-lan eth0.1 and when i send traffic from a host connected to one port to host connected at other end, soon all the memory is dried up and and kernel

Here is the proposed revision to the bridge utilities interface to the kernel. The driving force is that the existing interface can't easily be converted to 32/64 bit compat. Right now, the bridge-utils (brctl) tries to handle 32bit command on 64 bit kernel, but the code is limited to sparc and wrong. Here is what I am thinking. get version - not needed? get bridges -

Hi all, Can someone tell me where to find source code for RSTP for linux 2.6 kernel? Thank you in advance. -Marc.

Hi all, We use linux-2.4.20 in one of our products and we've found what looks to be a problem in the bridge module. (I know this is old code but we don't send our customers kernel upgrades unless we really have to!) The problem is that some of our bridges have become orphaned from the bridge module. Specifically ifconfig ourbridgename shows that the device "ourbridgename"

Hi, Is there any particular reason why the same physical port cannot be added to multiple bridges? Is it because of STP? If I am not using STP - can I change the code to have the same physical port in 2 VLANs? Is that a safe change? Thanks, Abhijit

Hi there, I am a student and working on a project where i need to configure RSTP (802.1w) on SUSE 10 kernel 2.6 so that i can able to analyse efficient link fail-over time, i have found STP configuration at ( http://linux-net.osdl.org/index.php/Bridge ) but coulnt find partticular RSTP configuration. i would appriciate if you could help me in this regard. cheers, was

Here is the scenario: I have one server with kernel 2.4.24 with a bridge br0 made of 2 interfaces, eth0 and tap0 (the last is an OpenVPN tunnel), and one remote computer connetting through tap0. If I assign a static IP to the remote computer, the bridge works perfecly (so I think the problem is not OpenVPN-related). If I start a DHCPd on the server and I configure the remote client to get the
