Your task is to identify and resolve the cause of connectivity failure with the remote office router R3. You have corrected the fault when pings from R2 to the R3 LAN interface are successful. R3. Currently EIGRP is configured on all routers R2. The remote office router (R3) was previously configured and all corporate subnets were reachable from R3.0. in the process of configuring EIGRP stub routing connectivity with the remote network devices off of R3 has been lost.0 subnets. .Correct Answer: Answer: Here is the solution below: Section: Layer 3 Technologies Explanation Explanation/Reference: QUESTION 79 JS Industries has expanded their business with the addition of their first remote office. Another network professional was tasked with implementing this solution.0. and the R3 IP routing table only contains 2 10. Once the issue has been resolved you should complete the task by configuring route summarization only to the remote office router R3. and R4 in the network. JS Industries is interested in using route summarization along with the EIGRP Stub Routing feature to increase network stability while reducing the memory usage and bandwidth utilization to R3. However.

You are tasked with identifying the cause of this fault and implementing the needed corrective actions that uses OPSF features and does not change the current area assignments. However. Currently OSPF is configured on all routers. Special Note: To gain the maximum number of points you must remove all incorrect or unneeded configuration statements related to this issue.Correct Answer: Answer: Here are the solution as below: Section: Layer 3 Technologies Explanation Explanation/Reference: QUESTION 80 ROUTE. You will know that you have corrected the fault when R4's loopback address (FEC0:4:4) can be seen in RTs IPv6 routing table. R4's loopback address (FEC0:4:4) cannot be seen in R1's IPv6 routing table. .com is a small IT corporation that has an existing enterprise network that is running IPv6 0SPFv3.

com. IT policy requires that all outbound HTTP traffic use the frame relay link when it is available. All other traffic may use either link. ROUTE.com has two connections to the Internet. a small IT company.Correct Answer: Answer: Here is the solution below: Section: Layer 3 Technologies Explanation Explanation/Reference: QUESTION 81 You are a network engineer with ROUTE. . one via a frame relay link and one via an EoMPLS link. No static or default routing is allowed.

100. Correct Answer: Answer: We need to configure policy based routing to send specific traffic along a path that is different from the best path in the routing table. You have been tasked with completing the implementation and ensuring that the network requirements are met. All traffic must use the shortest path that provides the greatest bandwidth.16. R4 has been added to the existing OSPF network to provide the interconnect between the OSPF and EIGRP networks.100. You may not remove or change any of the configuration . a small IT company. No static or default routing is allowed in either network. Section: Layer 3 Technologies Explanation Explanation/Reference: Here are the step by Step Solution for this: 1) First create the access list that catches the HTTP traffic: R1(config)#access-list 101 permit tcp any any eq www 2) Configure the route map that sets the next hop address to be ISP1 and permits the rest of the traffic: R1(config)#route-map pbr permit 10 R1(config-route-map)#match ip address 101 R1(config-route-map)#set ip next-hop 10.Choose and configure the appropriate path selection feature to accomplish this task. They have recently merged two organizations and now need to merge their networks as shown in the topology exhibit. The redundant paths from the OSPF network to the EIGRP network must be available in case of a link failure. One network is using OSPF as its IGP and the other is using EIGRP as its IGP. Two links have been added that will provide redundancy. A previous network engineer has started the merger implementation and has successfully assigned and verified all IP addressing and basic IGP routing.2 R1(config-route-map)#exit R1(config)#route-map pbr permit 20 3) Apply the route-map on the interface to the server in the EIGRP Network: R1(config-route-map)#exit R1(config)#int fa0/1 R1(config-if)#ip policy route-map pbr R1(config-if)#exit R1(config)#exit QUESTION 82 You are a network engineer with ROUTE.com.1.1. The network requirements state that you must be able to ping and telnet from loopback 101 on R1 to the OPSF domain test address of 172. You may use the Test Workstation to generate HTTP traffic to validate your solution.

16.commands currently on any of the routers. Reliability. that is 20000 / 10 = 2000) For R3 we use the show interface fa0/0 to get 5 parameters too R3#show interface fa0/0 For example we get Bandwidth=10000 Kbit. Load. . but the overall solution is the same. Reliability=255. Note: The actual OPSF and EIGRP process numbers may change in the actual exam so be sure to use the actual correct values. You may add new commands or change default values.100. Load=1. If the delay is 20000us then we need to divide it by 10. MTU=1500 bytes then we would redistribute as follows: R2#config terminal R2(config)# router ospf 1 R2(config-router)# redistribute eigrp 100 metric-type 1 subnets R2(config-router)#exit R2(config-router)#router eigrp 100 R2(config-router)#redistribute ospf 1 metric 1544 2000 255 1 1500 Note: In fact. Load=1. MTU=1500 bytes R3#config terminal R3(config)#router ospf 1 R3(config-router)#redistribute eigrp 100 metric-type 1 subnets R3(config)#exit R3(config-router)#router eigrp 100 R3(config-router)#redistribute ospf 1 metric 10000 100 255 1 1500 Finally you should try to “show ip route” to see the 172. MTU) of the s0/0/0 interface (the interface of R2 connected to R4) for redistribution: Section: Layer 3 Technologies Explanation Explanation/Reference: R2#show interface s0/0/0 Write down these 5 parameters. For example. R2(config-router)# distance eigrp 90 105 This command sets the Administrative Distance of all EIGRP internal routes to 90 and all EIGRP external routes to 105. Delay=20000 us. we get Bandwidth=1544 Kbit. Note: If the link between R2 and R3 is FastEthernet link. these parameters are just used for reference and we can use other parameters with no problem. Delay=1000 us. Reliability=255. which is smaller than the Administrative Distance of OSPF (110) -> the link between R2 & R3 will be preferred to the serial link between R2 & R4. which is better than R1 -> R2 -> R4. we must put the command below under EIGRP process to make traffic from R1 to go through R3 (R1 -> R2 -> R3 -> R4).1 network (the network behind R4) in the routing table of R1 and make a ping from R1 to this network. Correct Answer: Answer: First we need to find out 5 parameters (Bandwidth. notice that we have to divide the Delay by 10 because the metric unit is in tens of microsecond. Delay.
