You need to perform maintenance on one of your OSPF routers. You do not want the other OSPF routers on the network to forward traffic to this router dunng the maintenance window
Which OSPF configuration parameter would you implement to accomplish this task?
For maintenance scenarios where a router must remain operational but should not be used as a transit path for OSPF traffic, Junos OS uses the overload functionality.
OSPF Overload (Option B): When you enable overload under protocols ospf, the router advertises its own Link-State Advertisements (LSAs) with a maximum metric (65535) for all of its transit links.
Traffic Diversion: Because OSPF uses the Shortest Path First (SPF) algorithm to find the lowest-cost path, other routers in the network will see the overloaded router as an extremely high-cost path. They will calculate alternate routes, effectively moving transit traffic off the router while still allowing management traffic directed to the router's own interfaces.
Timeout Options: You can configure this to be permanent or set a timeout so that the router automatically resumes normal metric advertisements after a set period.
