Router R1 connects to a Frame Relay cloud using a multipoint subinterface, with ten PVCs associated with the subinterface.What command would make this router not use a DR, and dynamically discover OSPF neighbors?（）A. ip ospf network broadcastB. ip ospf network non - broadcastC. ip ospf network point - to - multipointD. ip ospf network point - to - multipoint non - broadcast

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?（）A. The no auto - summary command needs to be added under router eigrp 1B. The subnets keyword was not included in the redistribute command under router ospf 1C. The metric specified for the redistributed EIGRP routes is too large; m aking the EIGRP routes unreachable by router AD. The default - information originate command needs to be added under router ospf 1E. The administrative distance of either OSPF or EIGRP must be changed so that EIGRP has a higher administrative distanc e than OSPF
