The whole concept of a ring setup is that a single disaster can not
cause a network failure. For this setup I would only follow the ring
halfway.

So you get 2 chains:

Nagios --> A --> B --> C --> D
Nagios --> A --> B --> F --> E

Make sure you monitor each neighbor on each ring router to make sure the
ring is working as expected.

If you use dynamic routing you might want to monitor route changes
relevant for the proper operation of your ring setup.
