You may not remove or change any of the configuration commands currently on any of the routers. A previous network engineer has started the merger implementation and has successfully assigned and verified all IP addressing and basic IGP routing. No static or default routing is allowed in either network. Two links have been added that will provide redundancy. You may add new commands or change default values. . 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. R4 has been added to the existing OSPF network to provide the interconnect between the OSPF and EIGRP networks.16.1. 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 172.100. You have been tasked with completing the implementation and ensuring that the network requirements are met.com. All traffic must use the shortest path that provides the greatest bandwidth.QUESTION 21 You are a network engineer with ROUTE. a small IT company.
