問題文
An engineer configures an IP address on an interface and must decide where the address statement belongs. Which statement about interface structure in Junos is correct?
選択肢
- The address belongs directly to the physical interface, with no logical unit involved, and the family keyword is therefore written at the physical level.
- The address belongs to the loopback interface only.
- The address belongs to a logical unit of the physical interface, under a protocol family on that unit.
- The address belongs to the routing instance rather than to the interface at all, and the interface is then attached to that instance so that the address becomes reachable through it.
