Release Information

Statement introduced in Junos OS Release 17.3R1.


Enable a dedicated management virtual routing and forwarding (VRF) instance.

The management Ethernet interface (usually named fxp0 or em0) provides the out-of-band management network for the router. There is no clear separation between either out-of-band management traffic and in-band protocol control traffic, or user traffic at the routing-instance or routing table level. The management-instance configuration statement confines the management interface in a dedicated management instance, and it enables an administrative routing table dedicated to management tasks for the network device.

The name of the dedicated management instance is reserved and hardcoded as mgmt_junos; you cannot configure any other routing instance by the name mgmt_junos.


You must also configure the mgmt_junos routing instance at the [edit routing-instances] hierarchy level to use it.


This command has no options.
