In a doubly linked list, the last node is identified by its 'next' pointer. In a doubly linked list, each node contains a 'data' field, a 'next' pointer that points to the next node in the list, and a 'prev' pointer that points to the previous node in the list.

Here are the steps to identify the last node in a doubly linked list:

1. Start from the head node of the doubly linked list. The head node is the first node in the list and its 'prev' pointer is null.

2. Check the 'next' pointer of the current node. If the 'next' pointer is null, then the current node is the last node in the list.

3. If the 'next' pointer is not null, move to the next node by setting the current node to the node pointed to by the 'next' pointer.

4. Repeat steps 2 and 3 until the 'next' pointer of the current node is null. The current node is the last node in the doubly linked list.
