You wish to configure IPv6 support on a router which does not have any current IPv4 configuration.Which three steps are used to configure IPv6 with an accompanying IGP in JUNOS software? () A. set protocols isis inet6B. set routing-options router-id router-idC. set protocols ospf3 area 0 interface allD. set interface fe-0/0/1 unit 0 family inet6E. set routing-options ipv6-router-id router-id
The following output exists on Router R1, a router internal to area 1. What can you d etermine as true from the output of the show ip ospf database summary command?() A. The LSA was created by an ABR due to an area range command.B. The LSA was created by an ASBR due to a summary - address command.C. If cr eated by an area range command, the best metric for a subordinate subnet on that ABR must have been 11.D. None of the other answers is correct.
You have implemented mutua l route redistribution between OSPF and EIGRP on a border router. When checking the routing table on one of the EIGRP routers within the EIGRP routing domain, you are seeing some, but not all of the expected routes.What should you verify to troubleshoot this problem?（）A. The border router is using a proper seed metric for OSPFB. The border router is using a proper seed metric for EIGRPC. The administrative distance is set for OSPF and EIGRPD. The missing OSPF routes are present in the routing table of the border routerE. The subnet keyword on the border router in the redistribute OSPF command
What is the purpose of the OSPF router ID in a OR／BOR election?() A. It is used with the OSPF priority values to determine which OSPF router will become the DR or BOR in a point-to-point networkB. It is used with the OSPF priority values to determine which interface will be used to form a neighbor relationship with another OSPF routerC. It is used with the OSPF priority values to determine which router will become the DR or BOR in a multi access networkD. It is used to determine which interfaces will send Hello packets to neighboring OSPF routers
Refer to the exhibit. You have completed an OSPF implementation, and you are verifying OSPF operation. You notice that router A and router B are stuck in the two - way state. From the show ip ospf interface command output, what is the cause of this issue?（）A. All OSPF implementations must have at le ast one interface in area 0.B. You are attempting to run in the broadcast mode over an NBMA interface.C. Both routers are configured to function as a BDR; therefore, there is no DR router.D. Someone has changed the OSPF router ID; therefore you must clear the OSPF process.E. The OSPF priority is set to 0 on both routers; therefore neither can become the DR.
Which command enables OSPF for IPv6?() A. router ospf ipv6 process - idB. ipv6 ospf process - idC. router ospf process - idD. ipv6 router ospf process - id
An administrator types in the command router ospf 1 and receives the er ror message: "OSPF process 1 cannot start." (Output is omitted.) What should be done to correctly set up OSPF?() A. Ensure that an interface has been configured with an IP addressB. Ensure that IP classless is enabledC. Ensure that the interfaces can ping their directly connected neighborsD. Ensure that an interface has been configured with an IP address and is up
OSPF is configured over a Frame Relay network as shown in the exhibit. All PVCs are active.However, R1 and R3 fail to see all OSPF routes in their routing tables. The show ip ospf neighbor command executed on R2 shows the state of t he neighbors. What should be done to fix the problem? （）A. The ip ospf network broadcast command should be configured on each Frame Relay interfaceB. The ip ospf network non -broadcast command should be configured on each Frame Relay interfaceC. Th e ip ospf priority value on the spoke routers should be set to 0D. The ip ospf priority value on the hub router should be set to 0E. The neighbor command should be configured under the OSPF routing process on all routers
On your OSPF network, routers TK1 and TK2 belong to the same Ethernet network. However, they are unable to establish an adjacency over this link. While troubleshooting this problem, you issue the show ip ospf interface Ethernet 0command on each router. The output from these commands is displayed below:What is the underlying cause of the routers failing to become adjacent?（）A. The OSPF area is misconfigured.B. The priority on TK2 should be set lower.C. The cost on TK2 should be set lower.D. The hello and dead timers are misconfigured.E. You need to add a backup designated router to the network.F. The OSPF process ID numbers do not match.
A network administrator is troubleshooting the OSPF configuration of routers R1 and R2. The routers cannot establish an adjacency relationship on their common Ethernet link. The graphic shows the output of the show ip ospf interface e0 command for routers R1 and R2. Based on the information in the graphic, what is the cause of this problem?（）A. The OSPF area is not configured properly.B. The priority on R1 should be set higher.C. The cost on R1 should be set higher.D. The hello and dead timers are not configured properly.E. A backup designated router needs to be added to the network.F. The OSPF process ID numbers must match.
Which is true about OSPF router－id?() A.It is used for type 1 router LSAB.Highest IP address of the loopback is usedC.router-id needs to be matched on ospf neighborsD.router-id is 16 bit
