A company has a BGP network and a BGP route of 220.127.116.11/24 that should be propagated to all of the devices. The route is not now in any of the routing tables.

The administrator changes the access list to allow this route, but the route still does not appear in any of the routing tables. What should be done to propagate this route?
A. Clear the BGP session.
B. Use the release BGP routing command.
C. Use the service-policy command to adjust the QOS policy to allow the route to propagate.
D. Change both the inbound and outbound policy related to this route.

B. eigrp stub connected
C. eigrp stub summary
D. eigrp stub connected static
E. eigrp stub receive-only

B. They will appear in the OSPF routing table as type E2 routes.

D. All imported routes will be automatically summarized when possible.
E. Only routes with lower administrative distances will be imported.
When implementing OSPFv3, which statement describes the configuration of OSPF areas? Select the best response.
A. In interface configuration mode, the OSPFv3 area ID combination assigns interfaces to OSPFv3 areas.
B. In router configuration mode, the network wildcard area ID combination assigns networks to OSPFv3 areas.
C. In interface configuration mode, the IPv6 OSPF process area ID combination assigns interfaces to OSPFv3 areas.
D. In router configuration mode, the IPv6 OSPF interface area ID combination assigns interfaces to OSPFv3 areas.
When troubleshooting an EIGRP connectivity problem, you notice that two connected EIGRP routers are not becoming EIGRP neighbors. A ping between the two routers was successful. What is the next thing that should be checked? Select the best response.
A. Verify that the EIGRP hello and hold timers match exactly.

You have just completed an OSPF implementation. While executing your verification plan, you determine that R1 is not able to establish full OSPF adjacency with R2. The show ip ospf neighbor command output on R1 shows that R2 is stuck in the INIT state. What could be the cause of this problem? Select the best response.
A. DR and BDR election errors between R1 and R2.
B. The R2 router has not received the OSPF hello packets from the R1 router.
C. Mismatched interface maximum transmission unit (MTU) configuration between the R1 and R2.
D. Mismatched OSPF hello interval configuration between the R1 and R2.
E. Corrupted LSAs exchanges between the R1 and R2.
You have completed an OSPF implementation, and you are verifying OSPF operation. During this verification, you notice that the OSPF route of 172.16.10.0 is repeatedly appearing and disappearing from the routing table. Further investigation finds that the OSPF CPU utilization is very high and the routers are constantly performing SPF calculations. You determine that 172.16.20.2 is the source of the 172.16.10.0 route. Using the show ip ospf database router 172.16.20.1 command, you notice that when this show command is performed repeatedly, the contents of the LSA change every few seconds. What could be the cause of this problem? Select the best response.
A. OSPF authentication errors between some of the routers.
B. Two routers have the same OSPF router ID.
C. Issues with mistuned OSPF timers.
D. OSPF LSA pacing issues between some of the routers.
E. OSPF neighbor adjacency problems between some of the routers.
