Neighboring network devices

A non-transitory computer readable medium storing instructions executable by a processing resource to cause a computer to:

• determine a characteristic affecting a subset of a plurality of network devices;
• determine that:
• at least a first two of the subset are neighbors;
• and
• at least a second two of the subset are neighbors;
• and
• indicate which of a number of regions that each of the plurality of network devices are within based on the neighbor determination.

A method, comprising:

• determining a characteristic affecting a subset of a plurality of network devices:
• determining that:
• at least a first group of the subset are neighbors with each other;
• and
• at least a second group of the subset are neighbors with each other;
• and
• indicating which of a number of regions that the first group and the second group are within based on the determination which of the subset are neighbors;
• and
• performing a corrective action to prevent the characteristic from affecting the subset of the plurality of network devices.
