300-510試験無料問題集「Cisco Implementing Cisco Service Provider Advanced Routing Solutions 認定」
Refer to the exhibit. Customers A and C are experiencing packet drops when connecting to the application server. While troubleshooting the problem, the network engineer confines that the IS- IS Level-1/2 adjacency is up between routers A, B, C, and D and both customers can communicate with the database server without packet loss. Which action must the engineer take to resolve the issue?

Topology
Tasks
Configure and verify an OSPF neighbor adjacency between R1 and R2 in OSPF area 0 according to the topology to achieve these goals:
1. R1 pings the Loopback0 interface of R2. Use interface-level configuration to complete this task.
2. R2 pings the Loopback0 interface of R1. Use interface-level configuration to complete this task.
3. R2 receives a single summary route 172.16.100.0/22 for networks 172.16.100.0/24,
172.16.101.0/24, and 172.16.103.0/24.

Refer to the exhibit. A network engineer is investigating a report of packet drops between the branch site and the central site.
- The two sites are connected via OSPF and RSVP-TE tunnels.
- Traffic from the central site to the branch site is passing normally.
- Technicians at both sites successfully ping the loopback IP addresses on routers R1 and R2.
Which configuration corrects the packet-drop problem?

Refer to the exhibit. A network engineer just replaced five routers on this OSPF network. When the routing protocol is brought up, R5 cannot reach routes that originate on R1. The engineer verified that all connected links have established neighbor relationships. R5 reaches routes originating on R3 and R4. Which action resolves the issue?
