Refer to the exhibit. EIGRP has been configured on router D. Router C is performing mutual redistribution between EI GRP and OSPF. While verifying that the redistribution is functioning properly, you discover that while router C has all of the EIGRP routes in its routing table, router A does not have any routes from the EIGRP domain. What on router C may be the cause o f the problem?（） The no auto - summary command needs to be added under router eigrp 1。 The subnets keyword was not included in the redistribute command under router ospf 1。 The metric specified for the redistributed EIGRP routes is too large; m aking the EIGRP routes unreachable by router A。 The default - information originate command needs to be added under router ospf 1。 The administrative distance of either OSPF or EIGRP must be changed so that EIGRP has a higher administrative distanc e than OSPF。

使君从南来，五马立踟蹰。使君遣吏往，问是谁家姝？
