Lu sur le tracker de pyroute2 (https://github.com/svinota/pyroute2/issues/820) :

The eventlet module is one huge problem for NDB, tbh…

NDB is thread-based and I'm not sure it is compatible with eventlet at all. The machinery inside NDB uses also an SQL DB, and I have no idea if it will work correctly with eventlet.

If you plan to work with eventlet, then you may use plain IPRoute without async_cache, thus simple IPRoute.bind() if you need RTNL monitoring, or without any bind() at all if you don't need to monitor RTNL broadcasts.

Another alternative is to use NDB and eventlet in separate processes, connecting them via RPC (e.g. pyroute2-cli may be run as a service providing text/plain and json RPC).
