What does a static route in Junos specify?

A static route in Junos specifies a predefined path for IP traffic to a certain destination. This means that when configuring a static route, the network administrator manually sets the next-hop IP address or the exit interface for a specific destination subnet. The route remains consistent and does not change unless the administrator modifies it, unlike dynamic routes, which adjust automatically based on conditions in the network.

Static routes are commonly used for situations where the route to a specific destination is known and will not change frequently. This can be beneficial in a static network environment or when connecting to specific external networks. They provide a clear, straightforward way to dictate how packets should flow toward a destination, ensuring that traffic is efficiently routed according to the administrator's specification.
