Consider a network consist of 3 router (s1, s2, and s3). Network 137.220/16 connected to port 1 of s1. Port 2 of s1 connected to port 2 of s3. Port 3 of s1 connected to port 2 of s2. Network 67.56/16 connected to port 3 of s2. Port 1 of s2 connected to port 3 of s3. Network 128.119/16 connected to port 1 of s3. We want to specify the match+action rules at s3 so that s3 acts only as a relay for traffic between 137.220/16 and 67.56/16. In particular s3 should not accept/forward and traffic to/from 128.119/16. From the list of match+action rules below, select the rules to include in s3's flow table to implement this forwarding behavior. Assume that if a packet arrives and finds no matching rule, it is dropped.

Consider entries of the generalized forwarding table in a router: (1) match: src = *.*.*.*, dest = 3.4.*.*; action = forward(port2) ; (2) match: src = 1.2.*.*, dest = *.*.*.*; action = drop ; (3) match: src = 10.1.2.3, dest = *.*.*.* ; action = send to controller. Recall that a * represents a wildcard value. Now consider an arriving datagram with the IP source and destination address fields indicated below. For each source/destination IP address pair, indicate which rule is matched. Note: assume that a rule that is earlier in the table takes priority over a rule that is later in the table and that a datagram that matches none of the table entries is dropped.
