For the networks below $($and on the next page$),$ indicate how the switches forward packets and update

their forwarding tables. The initial switch forwarding table entries are shown in each diagram; use them

as provided. Indicate on which links the packet is transmitted by drawing an arrow next to each link

that carries the packet pointing from the host or switch that transmits the packet to the host or switch

that receives the packet. Indicate a switch learns an address by filling in the forwarding table as done

in class. If an existing forwarding table entry changes, correct the entry or cross it out and create a new

one.
