RIP and OSPF are configured on the routers as shown in the exhibit. R2 is configured with a two-way redistribution between RIP and OSPF domains. All routers can ping each other， but R1cannot see any of the OSPF routes in its routing table. What could the problem be？（） OSPF and RIP use the same major network 172.16.0.0. Therefore， the keywordsubnets is notrequired to redistribute protocols into OSPF。 Because OSPF has a longer mask for the same major network than RIP and because RIPversion 1 is being used， none of the routes learned from OSPF will be advertised into RIP。 The metric for the OSPF routes that are redistributed into RIP is too low， a fact that preventsOSPF routes from being advertised into RIP。 The process of redistribution of RIP into OSPF does not require any metric conversion， so thereis no need to define the metric using the default-metric command during the redistributio。
