1. **Network Diagram Explanation:**
- **Legend:**
- **Blue:** Represents IPv6 datagrams.
- **Red:** Represents IPv4 datagram (encapsulating the IPv6 datagram).
- **Routers and Paths:**
- **A (IPv6):** Starts the transmission (shown as blue arrow leaving A).
- **B (IPv6/IPv4):** Transits the datagram from IPv6 to IPv4 and sends it towards D through an IPv4 tunnel.
- **D (IPv4):** Continues the IPv4 transit towards E.
- **E (IPv6/IPv4):** Receives the IPv4 datagram and transits it back to IPv6.
- **F (IPv6):** Final destination of the datagram (indicated by a blue arrow arriving at F).
2. **Field Matching Exercise:**
- Perform the matching below to indicate the datagram field value and type at point **(c)**.

**Concept Explanation:**
Consider the mixed IPv4/IPv6 network shown below, where an IPv4 tunnel exists between IPv6 routers B and E. Suppose that IPv6 router A sends a datagram to IPv6 router F. IPv6 datagrams are shown in blue; the IPv4 datagram is in red (containing the encapsulated IPv6 datagram in blue).
