(Solved) : Figure Q5 Shows Connections Networks Organization Determine Content Forwarding Table Route Q33249062 . . .

Figure Q5(a) shows the connections of the networks of an organization. Determine the content of the forwarding table of Router R2 if address aggregation is used. Given the forwarding table of a router has the following entries Q5 (a) Destination NetworkSubnet Mask Next Ho Interface (6 marks) 158.132.152.0/22 Network A 158.132.155.0/24 Network B go g4 10.1.2.0/24 g2 10.1.2.2 10.1.2.1 To Internet 158.132.144.0/23 Network R1 R2 Network D 158.132.158.0/2 Figure Q5(a) Suppose a TCP segment with size 6000 bytes is passed to IP for delivery across two networks of the Internet. The first network (link) uses 20-bytes headers and has an MTU (Maximum Transfer Unit) size of 1500 bytes, the second network uses 10-bytes headers with an MTU of 1000 bytes.
