An engineer has been asked to limit which routes are shared by running two different areas within an OSPF implementation. However, the devices share a common link for communication.
Which virtual router configuration supports running multiple instances of the OSPF protocol over a single link?
To support running multiple instances of the OSPF protocol over a single link, OSPFv3 is required. OSPFv3 allows for multiple instances to be run on the same link by using instance ID numbers, ensuring that each instance's packets are correctly identified and processed. This feature is not available with OSPF (OSPFv2), ASBR, or ECMP.
Answer is B: Support for multiple instances per link—With OSPFv3, you can run multiple instances of the OSPF protocol over a single link. This is accomplished by assigning an OSPFv3 instance ID number. An interface that is assigned to an instance ID drops packets that contain a different ID.
