HI, well, the approach depends on your environment.
One way would be to get the topology of your network, pre-calculate routes and then reactively set the forwarding rules to implement the rules as the packet goes from switch to switch. In this case, the first packet's RTT may be miserable but then things improve dramatically. You can give the forwarding rules some timeouts and with this you may even get some benefit in terms of rules supported in your switch vs. rules needed in your network. You may want to take a simpler approach to start with: get the topology, precalculate your rules, install them in the switches w/o timeouts and there you are :-) Regards and keep safe and healthy, /Pedro A.
