I used simple_switch_stp but all i have to do is to ignore a determinate dpid and my algorithm is to check if in the event the dpid is different from that to ignore and than if is different i need to instantiate this switch with the dpid that i have from the event I use a the event "connectionup" i don't remember how this event it's called in ryu so how can i do this? My goal is to ignore a switch by its dpid is this the right way?
