I feel like the Checksum values are more for data integrity rather than matching, but I could be wrong.

Okay, the Area ID, timers, and Stub flag make sense as the critical matching fields. I'll double-check those in my notes before answering.

The Area ID, Hello/Dead intervals, and Stub flag - those are the three fields I'm confident must match for neighbors on the same segment.
