Question
**IPv6 Tunneling and Encapsulation** Consider the network diagram provided, featuring four IPv6 subnets connected by a mixture of router types: - **IPv6-only routers**: Shaded blue - **IPv4-only routers**: Shaded red - **Dual-capable IPv6/IPv4 routers**: Shaded blue with red interfaces connecting to IPv4 routers A host on **Subnet D** wishes to send an IPv6 datagram to a host on **Subnet A**. The assumed forwarding path is: **D --> E --> d --> c --> a --> C --> A** ### Network Diagram Explanation The diagram visualizes the network's structure, detailing connections among subnets and routers: - **Subnet D** (IPv6): Contains host D and router connections to IPv6/IPv4 subnet E. - **Subnet E** (IPv6/IPv4): Connects to routers `d`, `c`, and subsequently to Subnet A through router `a` and `C`. - **Subnet A** (IPv6): Contains host A, completing the message route from D. - IPv4 routes are clearly specified, showing transitions in the mixed IPv6/IPv4 environment. ### Task Identify the correct IPv6 destination address for the datagram originating from D to E. ### Options 1. **4985:EB89:6716:3F35:BF52:5ADE:113A:F5A3** 2. **C314:2371:5A31:E4C6:BE8F:351B:95B7:F4ED** 3. **C911:AA28:691D:57DE:4117:3619:5867:8848** 4. **8AB4:568F:BDF5:3B61:CFD8:AE58:8562:6699** Choose the appropriate address based on the network topology and path specifications.
