What are the purposes of an OSPF router ID? (Choose two.)
- To enable the SPF algorithm to determine the lowest-cost path to remote networks
- To facilitate router participation in the election of the designated router
- To facilitate the establishment of network convergence
- To facilitate the transition of the OSPF neighbor state to Full
- To uniquely identify the router within the OSPF domain
Explanation: The OSPF router ID does not contribute to SPF algorithm calculations, nor does it facilitate the transition of the OSPF neighbor state to Full. Although the router ID is contained within OSPF messages when router adjacencies are being established, it has no bearing on the convergence process.
