Hello Linux netdev experts, I have a board that has multiple Ethernet intefaces. two, eth0 and eth1 and 1G interfaces and two are 100M interfaces (eth2 and eth3). I create hsr interface, hsr0 using eth2 and eth3 using ip link command. Now I want to create a linux bridge as follows:- brctl addbr my_bridge brctl addif eth0 brctl addif hsr0 I connect a PC to eth0 interface and another hsr compliant device to eth2 or eth3. Is it a valid scenario? I see following description at https://wiki.linuxfoundation.org/networking/bridge where is mentioned that ============================= Adding devices to a bridge The command brctl addif //bridgename// //device// adds the network device device to take part in the bridging of “bridgename.” All the devices contained in a bridge act as one big network. It is not possible to add a device to multiple bridges or bridge a bridge device, because it just wouldn't make any sense! The bridge will take a short amount of time when a device is added to learn the Ethernet addresses on the segment before starting to forward. ============================= In this case hsr is already a 802.1D bridge and we are trying to bridge a bridge. So your expert opinion is needed. Thanks. -- Murali Karicheri Linux Kernel, Keystone
