Which expected route is missing from R1s route table based on the topology during the maintenance period?
The company and the company network have both been growing rapidly. Multiple adds,
moves and changes have been applied to the network.Your boss has asked you to
troubleshoot a recent OSPF synchronization problem that has arisen.
There have been synchronization problems at separate locations in the OSPF area 0. There
have been reported link failures during the rapid growth of the company network. You are
required to resolve the OSPF problem. OSPF must be able to converge when the network
changes.
Refer to the information above to answer the following question.
The R2 router has lost connectivity to R1. The following is R1s current route table:

Which two networks does the Core1 device have feasible successors for?
Refer to the exhibit. BigBids Incorporated is a worldwide auction provider. The network uses
EIGRP as its routing protocol throughout the corporation. The network administrator does
not understand the convergence of EIGRP.
Using the output of the show ip eigrp topology all-linkscommand, answer the
administrator’s questions.
