You can add a Print on node2 to verify. Also in Node1 you target the DST mac address of Node 3 so I doubt you hop through node2 indeed. Node...

> Do you mean I should first set DST to node2, then on node2 use EtherRewrite element and set it to node3? Well, if they're connected to a switch, how...

If it's about VM configuration to make the hop-by-hop wiring, it depends on your hypervisor, not Click.

If you use Click for packet processing you have to use it for everything. Do the SNAT inside Click, not with IPTables. Or use a virtual interface in ToDevice and...

IPRewriter, like a NAT, with something like RoundRobinIPMapper for pattern

Remember ECMP is per-packet, so you would break flows and VNFs would see part of multiple flows, so they can't run NAT etc. But if you don't want something flow-aware,...

To be flow-aware, but independent of load, you have HashSwitch. To do RoundRobin you need the aforementioned solution. Tom

Yes, with the usual Queue etc

You can check the explanation in the code at https://github.com/kohler/click/blob/master/lib/element.cc , but the first step is to be proficient with the usage of handlers themselves and Click in general before...

What do you mean by everything is fine when you use the library in elements? Click fully compiles? In which case do you get the undefined symbol then?
