SI S4 -D B S2 -2 S5 -E 8 SE 4- se The links between switches are labeled with weights, which are used by some routing applications The weights represent the cost of using that link. You are to find the path through S1-56 with lowest total cost (that is with smallest sum of weights), for each of the following transmissions. (Forexample, the lowest-cost path from A to E is A-S1-52-55-E,for a total cost of 1+2=3; the alternative path A-S1-54-55-E has total cost 5+1=6.) (a).A--->F(b). A--->D (C). A--->C (d). Give the complete forwarding table for S2, where all routes are selected for lowest total cost. 5) Suppose we have the following three Class CIP networks, joined by routers R1R4. There is no connection to the outside Internet. Give the forwarding table for each router. For networks directly connected to a router (eg 200.0.1/24 and R1), include the network in the table but list the next hop as direct or local R1-200.0.1/24 R4 -R2- 200.0.2/24 R3 200.0.3/24
