address, 2041:0000:140F:079F:0000:0000:0000:131B? c) Suppose a router has built up the routing table shown in Table below: SubnetNumber SubnetMask NextHop 255.255.254.0 Interface 0 255.255.254.0 Interface 1 128.96.170.0 128.96.168.0 128.96.166.0 255.255.254.0 R2 255.255.252.0 R3 128.96.164.0 (default) R4 The router can deliver packets directly over interfaces 0 and 1, or it can forward packets to routers R2, R3, or R4. Assume the router does the longest prefix match. Describe what the router does with a packet addressed to each of the following destinations: i. 128.96.167.151. ii. 128.96.163.151 iii. 128.96.169.192.
