  A. DLCI

• Question 315:

  You are a network engineer with ROUTE.com, a small IT company. They have recently merged two organizations and now need to merge their networks as shown in the topology exhibit. One network is using OSPF as its IGP and the other is

  using EIGRP as its IGP. R4 has been added to the existing OSPF network to provide the interconnect between the OSPF and EIGRP networks. Two links have been added that will provide redundancy.

  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 172.16.1.100. All traffic must use the shortest path that provides the greatest bandwidth. The redundant

  paths from the OSPF network to the EIGRP network must be available in case of a link failure. No static or default routing is allowed in either network.

  A previous network engineer has started the merger implementation and has successfully assigned and verified all IP addressing and basic IGP routing. You have been tasked with completing the implementation and ensuring that the network

  requirements are met. You may not remove or change any of the configuration commands currently on any of the routers. You may add new commands or change default values.

  A. Check the answer below

  First we need to find out 5 parameters (Bandwidth, Delay, Reliability, Load, MTU) of the s0/0/0 interface (the interface of R2 connected to R4) for redistribution:R2#show interface s0/0/0Write down these 5 parameters, notice that we have to divide the Delay by 10 because the metric unit is in tens of microsecond. For example, we get Bandwidth=1544 Kbit, Delay=20000 us, Reliability=255, Load=1, MTU=1500bytes then we would redistribute as follows:R2#config terminalR2(config)# router ospf 1R2(config-router)# redistribute eigrp 100 metric-type 1 subnetsR2(config-router)#exitR2(config-router)#router eigrp 100 R2(config-router)#redistribute ospf 1 metric 1544 2000 255 1 1500 Note: In fact, these parameters are just used for reference and we can use other parameters with no problem.If the delay is 20000us then we need to divide it by 10, that is 20000 / 10 = 2000) For R3 we use the show interface fa0/0 to get 5 parameters tooR3#show interface fa0/0For example we get Bandwidth=10000 Kbit, Delay=1000 us, Reliability=255, Load=1, MTU=1500 bytes R3#config terminalR3(config)#router ospf 1R3(config-router)#redistribute eigrp 100 metric-type 1 subnetsR3(config)#exitR3(config-router)#router eigrp 100R3(config-router)#redistribute ospf 1 metric 10000 100 255 1 1500 Finally you should try to “show ip route” to see the 172.16.100.1 network (the network behind R4) in the routing table of R1 and make a ping from R1 to this network. Note: If the link between R2 and R3 is FastEthernet link, we must put the command below under EIGRP process to make traffic from R1 to go through R3 (R1 -> R2 -> R3 -> R4), which is better than R1 -> R2 -> R4.R2(config-router)# distance eigrp 90 105This command sets the Administrative Distance of all EIGRP internal routes to 90 and all EIGRP external routes to 105, which is smaller than the Administrative Distance of OSPF (110) -> the link between R2 and R3 will bepreferred to the serial link between R2 and R4.Note: The actual OPSF and EIGRP process numbers may change in the actual exam so be sure to use the actual correct values, but the overall solution is the same.
