Figure $1$ shows a small network using point$-$to$-$point links. Node G is a gateway to a larger

network. The cost of using each link is marked beside the link. The network topology and

traffic are fairly stable, and the network uses fixed routing. Draw up the routing table for

node C$,$ showing the best link for traffic to each destination in this network and for traffic

to destinations outside this network. Also show an alternative for each destination, for use

when the best link is not available
