Networking is a fancy word for relationship building. With that in mind I think you also need to think about quality over quantity of people you want to stay connected with and build relationships with.
Curating a list of people you genuinely want to keep in touch with will help. Connecting on LinkedIn is helpful and I do like the idea of reminders.
You can also keep in touch more organically. My mentor from college and I are still in touch and although we're not super close or in touch frequently we send each other occasional messages to check in. This is the same with previous bosses who have since referred me to other companies and helped me get hired elsewhere.
Sometimes a message and building relationships over time can be super simple over text, email or LinkedIn to say "I was in Starbucks today and someone ordered 3 pumps of vanilla in their coffee. It made me think of you ;-) How are you doing? Hope all is well" OR "I just booked a trip to X location and I remembered you visited a couple of years ago. How are you doing? Hope all is well" OR "I read this article and it made me think of our conversation at the X conference. HYPERLINK. How are you doing? Hope all is well"
This is far more organic and thoughtful than a quarterly update on your own progress and shows you value the person and their uniqueness and not their position.
