A network includes a RIPv2 domain, an EIGRP domain, and an OSPF domain. Each pair of routing domains has multiple routers redistributing routes between the p air of domains. The design requires that the redistribution configuration avoid matching based on prefix/length because of the trouble in maintaining such configurations.Which one of the following tools can be used in all three routing domains to attem pt to prevent domain loops?（）A. Setting route tagsB. Setting the default administrative distance differently for internal and external routesC. Setting administrative distance differently per routeD. Setting metrics much higher for all ext ernal routes than for all internal routes

Ten routers, R1 through R10, connect in a partial mesh over Frame Relay. For the mesh, R1 and R2 have PVCs connected to all other routers, but Routers R3 through R10 act as branch routers, with only two PVCs - one to R1 and one to R2. The routers u se IP subnet 10.1.1.0/24, with addresses 10.1.1.1, 10.1.1.2, and so on, through 10.1.1.10, respectively. The routers all use Inverse ARP to learn Frame Relay mapping information. All routers use a multipoint subinterface with network type point - tomultip oint nonbroadcast. A co - worker‘s implementation plan lists lots of configuration commands related to this design. The design states that all hosts should be able to ping all other hosts.Which commands are required for proper functioning of OSPF in this case?（）A. frame - relay map commands on R3 - R10 referencing the other routers in this groupB. Nine OSPF neighbor commands on each routerC. Nine OSPF neighbor commands on R1 and R2, with only two such commands on R3 - R10D. R1 and R2 with ip ospf prio rity 1 commands to ensure they become DR and BDRE. R3 - R10 with ip ospf priority 0 commands to ensure they do not become DR or BDR

You have implemented mutual route redistribution between OSPF and EIGRP on a border router. When checking the routing table on one o f the OSPF routers within the OSPF routing domain, you are seeing some, but not all of the expected routes.Which two things should you verify to troubleshoot this problem?（）A. The border router is using a proper seed metric for OSPFB. The border ro uter is using a proper seed metric for EIGRPC. The administrative distance is set for OSPF and EIGRPD. The missing EIGRP routes are present in the routing table of the border routerE. The subnet keyword on the border router in the redistribute EIG RP command
考题
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?（）A. OSPF authentication errors between some of the routersB. Two routers have the same OSPF router IDC. Issues with mistuned OSPF timersD. OSPF LSA pacing issues between some of the routersE. OSPF neighbor adjacency problems between some of the routers
考题
What are three characteristics of the OSPF routing protocol?()
A. It converges quickly.B. OSPF is a classful routing protocol.C. It uses cost to determine the best route.D. It uses the DUAL algorithm to determine the best route.E. OSPF routers send the complete routing table to all directly attached routers.F. OSPF routers discover neighbors before exchanging routing information.
