Re: [Bridge] Error in Bridge Settings!!

[Etienne Pretorius]

Let me first explain that I have the same problem in my Ethernet bridge setup. What I have determined, that there is a loop in my network but STP is preventing a packet broacast storm. I have switches instead of hubs but my primary bridge is broadcasting packets somehow, because when I unplug the primary's Ethernet from our internal network then those messages stop appearing. I am in the process of re-setting up that bridge so that *hopefully* I wont be seeing this message in future. I wander if it might be the HUBs you using.... they might be broadcasting any packet to all ports and so your bridge will receive its own packets back to it? Like I said - I have the same problem, but the setup still works and I am trying to remove loops in my network to see if that *really* is the cause to the error message. Kind Regards Etienne Kirti S.

My plan is to have the ‘redundant’ BRIDGE working and then I will add ‘Shorewall’ Firewall to these two servers. On both machines, I have included the following lines in ‘/etc/rc.local’ so that the BRIDGE will be ACTIVE after BOOT:   /etc/rc.local =========  # Setup BRIDGE (First Bridge)  brctl   addbr       tibbr1  brctl   addif        tibbr1  eth0  brctl   addif        tibbr1  eth1  ifconfig   tibbr1  up  ifconfig   tibbr1  12.21.237.2   netmask   255.255.255.0  brctl   setageing   tibbr1  300  brctl   stp   tibbr1    on  brctl   setbridgeprio   tibbr1   100  brctl   setpathcost  tibbr1  eth0  100  brctl   setpathcost  tibbr1  eth1  100  reboot   ========= Similar lines are included in the second server except the bridge name is ‘tibbr2’, IP addr is 12.21.237.4 & bridge & path costs are 200.
