Topology

Tasks
Configure and verify the OSPF neighbor adjacency between R1 and R2 in OSPF area 0 according to the topology to achieve these goals:
1. Configure OSPF cost to 15 on R1 and R2.
2. Redistribute all the static routes defined in R1 and R2 to the OSPF routing protocol.
3. Set the OSPF hello interval to 5 and the OSPF dead interval to 10 between R1 and R2.

Question 3

Refer to the exhibit. An organization s network recently experienced several significant outages due to device failures. The network administrator just moved the network devices to a new central data center, and packets are switched using labels. The administrator Is now implementing NSF on the network to reduce potential risk factors in the event of another outage.
Which task must the administrator perform on each router as part of the process?

A. Implement MPLS to forward packets while the RIB updates after a faliover. B. Copy the router s existing state information and share the file with its peers to enable BGP soft resets C. Implement Graceful Restart to mitigate the delay in MPLS LDP synchronization when the IGP starts up. D. Remove route filtering to speed repopulation of the link-state database
