1. Come up with the routing tables for all the routers: A, B, C, D, E, F, and G. Host 70.0.0.9 must receive his packets only from router E. All other traffic to network 70.0.0.0 may arrive from other routers. Router H is the router used to access the Internet. Your routing tables must use the shortest possible route.

2. Explain fragmentation as it relates to datagrams. Why is it necessary? Where does it occur? When and where are the fragments reassembled? Give examples and be as specific as possible.

If someone can explain and help me? Thank you

this is for computer science the instructions are in my caption!
