Maximal number of hops (path cost) in Thread / OpenThread

What is the maximal number of hops (or path cost) allowed by Thread specification. How many hops are supported by OpenThread?

I found two similar questions (link1, link2) but answer is different (maybe even outdated?).

Solution

  • Thread specifies a maximum path cost of 16 between routers. Link cost between routers can be 1, 2, or 4. Links to end devices are not included in the path cost calculation.
