End-to-end authentication and encryption are desired between two hosts. Draw figures similar to Figure 8.8 in the PLE (Figure 9.8 in the textbook) that show each of the following.

1)Transport adjacency with encryption applied before authentication.

2)A transport SA bundled inside a tunnel SA with encryption applied before authentication.

3)A transport SA bundled inside a tunnel SA with authentication applied before encryption.
