I reposted becouse the diagram was incomprensible :-( maybe this is out of topic, but: i have an embedded system with two lan adapters running linux, i would like to wire a lot of it in a "daisy chain way": sys1 sys2 sysn-1 sysn +---------+ +---------+ +---------+ +---------+ |eth0 eth1| |eth0 eth1| |eth0 eth1| |eth0 eth1| +---------+ +---------+ +---------+ +---------+ | | | | | | | +--------+ +--x--+ +--x--+ +--x--+ | switch | cross-cables +--------+ This approach eliminate the need of expensive switches. It's feasible? how (bridging, routing?) There is a limit of chaining devices number? Any help will be appreciated.
