similar to: [Bridge] 802.1D/Linux STP issue

hi list! i'm trying to find a convenient way to build a redundant filtering bridge under linux i looked at carp project, but carp doesn't support bridge now i thing the most appropriate way is using stp or rstp it seems that 2.6 kernel supports stp but what about rstp? I read some docs about stp, but they are rather outdated (2001 and kernel 2.2) there are several problems indeed: *

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

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. I need to use STP (ideally MST) on centos 6.3. I've read that it's supported in linux kernel as part of IEEE 802.1Q standard, but can't find any information on configuring miltiple spanning trees. So - help? suggestions? rtfm (as long as you point me to actual manual)? anything? Thank you, - V

Hi, I have downloaded rstp from sourceforge and I get a segfaults when running the daemon. This is the line where the problem arises: TST(ifc->master->stp_up,); just at the beginning of function: void bridge_bpdu_rcv(int if_index, const unsigned char *data, int len) in file bridge_track.c -------------- next part -------------- An HTML attachment was scrubbed...

Hello, I am a student considering participating in Google Summer of Code program. I came across Stephen Hemminger's idea of implementing a RSTP posted on http://developer.osdl.org/dev/soc/ and found it interesting. In attachment there's my proposal, which I just submitted to google. Please share your comments. -- tadeusz andrzej kad?ubowski -------------- next part --------------

Hi, I'm a student in a trainning period and I have to implement a RSTP in a embedded Linux. I wonder if someone knows if it exists a version of bridge-utils who can made this or if it's possible to modify my actual version (bridge-utils-1.0.6) to do that and how ? Thanks in advance. PS : sorry for my english it's not my natural language ^^.

This might be a crazy idea, but it just popped into my head, and I wanted to know if it''s possible. Perhaps not possible right now, but possible in a theoretical sense. Is it possible that puppet could be modified to be used to manage switches that have a command line based interface? When I manage our Allied Telesis switches (which have a CLI similar to cisco IOS) I wonder if I could

Hi, I am working on implementations of RSTP and MSTP. It would be of great help of me if you could provide me with a robust open source implementation of RSTP and MSTP which I can have a look upon and some guidelines on how to implement/configure on Linux. Looking for a positive response soon. Regards, Abhishek. DISCLAIMER:

Hi, I'm trying to modify the stp kernel files in order to implements the RSTP. I've already modify the bpdu format like this : ------------------------------------------------------------------------------------------------------------------------------------ typedef struct { int topo_change = 0; int proposal = 0; int port_role[2] = {0,0} ; //role du port ?metteur du BPDU

I am interested in finding out about the current efforts in adding RSTP (802.1w) support to the current bridging module (more interested in 2.6 tree). I am a developer and can offer my help in either developing the code, porting over work from a 2.4 tree, or in a testing capacity. I would appreciate it if people who are working on this can contact me and let me know the status of the

As I start on STP enhancements, it is worth asking, how many users of bridge actually use STP, and if so how big a network is involved.

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

Hi, I am configuring some servers in a high availability setup. The servers are connected to two switches with two LAN cards in each server. The two switches are connected directly to each other. The servers are configured to bridge eth0 and eth1 with spanning tree. Usually this makes sure eth1 is disabled, unless something happens to eth0. This way I can have one IP address on each server. Now

Hello Satya, > RSTP daemon runs in application and stops the kernel stp and informs > to pass the packets to application layer. > RSTP daemon waits in raw socket with stp filter. > You just need to change the a bit code for port wise that all. ok thanks, do I need the DSA (Distributed Switch Architecture) driver support to distinguish from which port a frame arrived?

Hi all, Reading docs about using bridges in a KVM environment, I have a doubt about activating STP or not in a KVM host. What advantages and disadvantages have?? If I will want to install some kvm guests that use multicast address for certain services, is it recommended to enable STP? Thanks.

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 all, We are facing a problem with STP implementation. We have only 2 switches. Thats the constraint, but we feel STP should work. Background: We have developed a layer 2 switch. This uses Cirrus logic's ep9301 processor, embedded Linux 2.4.21 kernel as the OS and zarlink's switch controller. The observation: 1)we have 2 switches, switch A and switch B 2)port 1 and port 2 of switch

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.
