Are my assumptions about this command correct?
-The passive-interface command can be implemented at the global, interface, and router config modes.
- When implemented in the global mode, all interfaces don't send or listen to routing updates.
-When set at an individual interface, that individual interface ignores routing updates.
-When set at the router config mode, you can either choose passive mode for individual or all interfaces for that specific routing protocol.
The only one I'm not sure about is the global config version. Is it valid?
