It's developed to provide loop-free redundancy links to Ethernet-based networks. I can't

When we create an L2 loop on a bridge in netns, we will see packets storm even if STP is enabled. # unshare -n # ip link add br0 type bridge # ip link add veth0 type veth peer name veth1 # ip link set veth0 master br0 up # ip link set veth1 master br0 up # ip link set br0 type bridge stp_state 1 # ip link set br0 up # sleep 30 # ip -s link show br0 2: br0:

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, Finally, I have installed openvswitch from source to two CentOS hosts: one 6.x and other 7.x. I will do some tests using openvswitch bridges to my KVM machines. One of these tests is to add a wlan0 adapter from comandline but only when this wlan0 is associated with a ssid without assign an IP. Is this posible? Do I nees to add some ebtables like, for example, Debian's wiki

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

Hi, I've got a small tinc network (switched) set up and it usually works fine. But sometimes i get echos from my own broadcasts and sometimes this even leads to a broadcast storm (two nodes forwarding the broadcasts in circle, thus flooding the whole network with copies of the same packet). I'm currently unsure on how to debug this using tinc. So my questions are: - How does tinc handle

Hello, when talking about networking in hypervisors, it's easy to distinguish the two classic configurations, NAT and bridged, and the official libvirt wiki does exactly in this way here [1]. NAT networking is already configured by libvirt creating a bridge called libvirt0, while bridged networking have to be configured manually by the user. The libvirt0 bridge for NAT networking is default

I've got a run of Shielded Twisted Pair (4 conductors) which used to be a Token Ring Network drop and I'm not using it anymore. Would it be decent to replace the ends with normal analog phone connectors and use it for a phone extension, or is STP unsuitable for that? Thanks Steve

if I just connect two similar port say both 10 gb of one switch to another = symmetric bridge with stp enabled on both bridge , stpstate of all four po= rts always remain forwarding. ( may be because all four of them are either root or desginated port in abo= ve setup) should I except that one port atleast will get into blocking state , if i c= onnect two non-similar ports together say a 10gb

Hello World, I have met tinc a few days ago and started with a simple connection between 2 machines. I have fallen in love witht tinc, it's very simple to configure, although I haven't used tinc in production yet, because of its simplicity I think it's very robust. I also like how the configuration is organized with hosts/ directory, up/down scripts. Thank you for such a great tool.

Running CentOS 5.4 x64. Have successfully bridged eth2 with br2 by following the instructions here: http://wiki.libvirt.org/page/Networking (under the RHEL section) Have been running several KVM VMs successfully via this bridge. I am now trying to bridge additional interfaces by using the same routine. Each bridge is named to correspond with the ethX device its bridged with. Example of

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.

Greetings, I've setup an vm with openwrt in it, defined a isolated lan between the vm and the host and booted the vm up. I see the vm is up, made sure the vnic is visible in both the host and guest and added it to the br in the guest. I've issued an dhcpd call on the vnic (labeled vnic0) in the host and got an ip, see: dagg@NCC-5001D ~ $ dhcpcd vnet0 DUID
