Generаlized fоrwаrding: specifying а flоw table entry (a). Cоnsider the three-node network below, that uses flow-based generalized forwarding (e.g., as in OpenFlow) in the network's routers. In the question below, we'll want to create match+action entries in the flow table at router r2, with three ports labelled 1,2,3 (in black). In the question, matches are constrained to be over only four fields: the IP source address, the IP destination address, the upper-layer protocol field of the IP datagram, and the destination port number of the transport-layer segment. The actions are either to drop or to forward(i), that is, to forward a matching packet on port i. The default action (unless stated otherwise) is that if a packet doesn't match a rule, it will be dropped. (a) Suppose we want to implement the following rule: r2 should act as a firewall, only allowing UDP traffic from r3 to the 22.33/16 network. Specify a single flow table row entry to implement this rule, indicating the column entries for that row. The * is a wildcard match, which matches everything.
