2.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.

R2 becomes the feasible successor for Network AB. R4 becomes the successor for Network A and will be included in the routing table. No feasible successor will be selected a s the advertised distance from R2 is higher than the feasible distanceC. R2 becomes the successor and will be placed in the routing table. R4 becomes the feasible successor for Network AD. R2 becomes the successor and will be placed in the routing t able.
