Task $4$

Given is the network in Figure $4\mathrm{.}1$ with $5$ SDN Switches $($Swx$),1$ SDN Controller $($Ctrl$)$ and $4$

interconnected IP subnets with Hosts A$,$ B$,$ C$,$ and D$.$ The SDN Switches are connected via the Ports

Routing is to be performed between the IP subnets $($with the host computers$),$ with the routing criterion

being the shortest path $($minimum number of SDN switches traversed$).$ Please complete the missing

entries in the flow tables of SDN Switch $2.$

For destination subnets $2100$:$1$:$\frac{\text{:}}{64}$ or $2200$:$2$:$\frac{\text{:}}{64}$ or $2300$:$3$:$\frac{\text{:}}{64}$ or $2400$:$4$:$\frac{\text{:}}{64}$
