Solution
The field in the IPv6 header that points to optional network layer information that is carried in the IPv6 packet is the "Next Header" field.
Here's a step-by-step explanation:
-
An IPv6 packet consists of a header and payload. The header contains various fields that provide information about the packet.
-
One of these fields is the "Next Header" field. This field is used to indicate the type of header that immediately follows the IPv6 header, which could be an extension header or the upper-layer header.
-
Extension headers carry optional Internet-layer information. They are not examined or processed by any node along a packet's delivery path until the packet reaches the node (or nodes) identified in the Destination Address field of the IPv6 header.
-
Therefore, if there is optional network layer information carried in the IPv6 packet, it would be indicated in the "Next Header" field.
