You are running OSPF between two ERX Edge Routers across an OC－12c link with HDLC encapsulation.How many designated routers are present for this link?()
A.0B.1C.2D.3
考题
Process OSPF 1 is redistributing routes from process OSPF 2. Which of the following methods may be used to set the metrics of the redistributed routes?()
A. Let the metrics default.B. Use each redistributed route‘s OSPF metric using the redistribute command‘s metric transparent keywords.C. Set the metric using the default - metric router subcommand.D. Redistribution is not allowed between two OSPF p rocesses.
考题
Refer to the exhibit. Router B and router C are performing mutual redistribution between OSPF and EIGRP, and their default metrics are configured the same. Router D has equal cost paths to networks where both paths are not r eally equal cost. For example, network 172.16.54.0 shows equal cost through both router B and router C, though in reality the cost is greater using router C. Other routers, though not shown, are connected to the 172.16.54.0 and 172.16.55.0 networks, and the same issues exist to those routers and the networks connected to them. What can be done so that data will be routed along the most optimal path in the network? （）A. Redistribute connected interfaces on router B and router CB. Set the maximum nu mber of equal cost paths to1 in all routersC. When redistributing EIGRP into OSPF, set the external metric type to type E1D. Adjust the default metrics in router B and router C so that the values are different in each routerE. None of these solut ions will fix the problem. Migrate to a single dynamic routing protocol
考题
