JN0-649 Exam - Question 43


Click the Exhibit button.

You have scheduled maintenance operations for one of the devices in your OSPF network.

Referring to the exhibit, which three statements are correct? (Choose three.)

Show Answer
Correct Answer: BCD

The configuration in the exhibit shows that the OSPF overload bit is set, which is used to make a router less preferable for transit traffic. This means that R1 participates in OSPF routing, but it is discouraged from being used for forwarding transit traffic. The correct statements are: 1) Any traffic destined for networks that terminate on R1 will still be forwarded to R1, as the overload bit affects only transit traffic and not traffic destined for local networks. 2) The metrics for all transit interfaces on R1 are set to the maximum value of 65,535, making R1 an undesirable path for transit traffic. 3) R1 participates in OSPF routing but does not send or receive transit traffic unless there are no alternatives.

- Configure the local routing device so that it appears to be overloaded. You might do this when you want the routing device to participate in OSPF routing, but do not want it to be used for transit traffic. - Traffic destined to directly attached interfaces continues to reach the routing device. - When configured, the transit interface metrics are set to the maximum value of 65535. https://www.juniper.net/documentation/us/en/software/junos/ospf/topics/ref/statement/overload-edit-protocols-ospf.html https://www.juniper.net/documentation/us/en/software/junos/ospf/topics/topic-map/configuring-ospf-route-control.html#id-understanding-ospf-overload-function
