Specifying Whether Inactive Routes Are Removed from the Routing or Forwarding Table

Static routes are only removed from the routing table if the next hop becomes unreachable. The next hop will become unreachable if there are no contributing routes. To have an aggregate route remain continually installed in the routing and forwarding tables, include the passive option when configuring the route:

[edit routing-options aggregate (defaults | route)] 

passive; 

Routes that have been configured to remain continually installed in the routing and forwarding tables are marked with reject next hops when they are inactive.

To explicitly remove aggregate routes when they become inactive, include the active option when configuring routes. Include this option when configuring an individual route in the route portion of the aggregate statement to override a retain option specified in the defaults portion of the statement.

[edit routing-options aggregate (defaults | route)] 

active; 

For a list of hierarchy levels at which you can configure these statements, see the statement summary sections for these statements.
