From a consumer view I think we should be conservative and not add any additional commands that operates in an area where there already exists well known commands. Not sure i understand what new features you are contributing, but the sound of it i guess it has to do with IP routing and fib’s. If this is the case i would like to see this introduced in to route(8) and netstat(1) /Peter > 16 aug. 2020 kl. 11:11 skrev Alexander V.
