This looks strange to me. You do something here that is putting you in the
warranty void bucket. Please configure your interfaces properly. Do not
play games by injecting route commands to install cloning routes for a
different network.

In short make sure that vport11 and vio0 share a common subnet and can
talk directly to each other. After that ripd may actually work as well.
