Consider the following arrangement of switches and destinations. Give forwarding tables (in neighbor form) for S1-S4 that include default forwarding entries; the default entries should point toward S5

Exercise 3: 3.0 Consider the following arrangement of switches and destinations. Give forwarding tables (in neighbor form) for S1-S4 that include default forwarding entries; the default entries should point toward S5. Eliminate all table entries that are implied by the default entry (that is, if the default entry is to S3, eliminate all other entries for which the next hop is S3).

Exercise 4: Four switches are arranged as below. The destinations are S1 through S4 themselves.

 (a). Give the forwarding tables for S1 through S4 assuming packets to adjacent nodes are sent along the connecting link, and packets to diagonally opposite nodes are sent clockwise.
