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?()
- A、OSPF and RIP use the same major network 172.16.0.0. Therefore, the keywordsubnets is notrequired to redistribute protocols into OSPF
- B、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
- C、The metric for the OSPF routes that are redistributed into RIP is too low, a fact that preventsOSPF routes from being advertised into RIP
- D、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 redistribution
