Features and Enhancements
This section covers a brief description of the features and enhancements introduced in this release. It also includes links to detailed documentation, where available.
| Feature | Description |
|---|---|
|
cnBNG now supports DHCPv6 raw options, enabling you to set any DHCPv6 option type, including Mapping of Address and Port using Encapsulation (MAP-E) for scenarios such as migration to cloud native BNG. |

This feature ensures a smoother and more efficient onboarding process for new subscribers by reserving the first IP address in the allocated chunk for gateway functionalities. |
|
|
This feature allows each IPv6 host to generate its own address using local and router-advertised information, simplifying the integration of new IPv6 hosts without extensive configuration. |

Software Integrity Verification
To verify the integrity of the software image you have from Cisco, you can validate the SHA512 checksum information against the checksum identified by Cisco for the software.
Image checksum information is available through Cisco.com Software Download Details. To find the checksum, hover the mouse pointer over the software image you have downloaded.
The following screenshot is an example of a cnBNG CP release posted in the Software Download page.
At the bottom you find the SHA512 checksum, if you do not see the whole checksum you can expand it by pressing the "..." at the end.
To validate the information, calculate a SHA512 checksum using the information in Table 1 and verify that it matches either the one provided on the software download page.
To calculate a SHA512 checksum on your local desktop, refer to the following table.

If the SHA512 checksum matches, you can be sure that no one has tampered with the software image or the image has not been corrupted during download.
If the SHA512 checksum does not match, we advise you to not attempt upgrading any systems with the corrupted software image. Download the software again and verify the SHA512 checksum again. If there is a constant mismatch, please open a case with the Cisco Technical Assistance Center.
