Hi everyone, I did the first part of this (great) tutorial and now i'm in the routing part and i'm wondering few things :
1 - why do we need 2 switch for this topology ? one should be enough right ? 2 - In the switching part, one didn't care about ARP reply/request... but here in routing mode we should, so here is my question : how do you craft ARP reply ? In the controller after a packet In message by sending a packet out message to the switch ? Or is there a way to push a flow that would match the ARP request and with actions would send an ARP reply ? 3 - What about ARP request ? When one need to replace ethernet destination... the controller should do it by using a packet out ? Thanks for your help Arnaud M
