A. redistribute eigrp 10 metric 121

B. redistribute rip metric 121

C. default - metric 121

D. distance 121 10.1.1.6 0.0.0.0

A. router rip

B. router eigrp 10

C. redistribute eigrp 10

D. redistribute rip

E. default - metric 10000 100 255 1 1500

F. default - metric 5

B. misconfigure the metric- type option in t he redistribute command to type - 1.

C. miss the subnet option in the redistribute command.

D. miss the tag option in the redistribute command.

During the redistribution process configured on RTA, some of the EIGRP routes, such as 10.1.1.0/24 and 10.2.2.0/24,are not being redistributed into the OSPF routing domain. Which two items could be a solution to this proble m?（）

A. Change the EIGRP AS number from 100 to1 in the redistribute command.

B. Add the subnets option to the redistribute command.

C. Change the metric - type to2 in the redistribute command.

D. Configure the redistribute command under router eigrp 1 i nstead.

E. Change the metric to an EIGRP compatible metric value (bandwidth, delay, reliability, load, MTUs) in the redistribute command.

Refer to the exhibit. A new TAC engineer comes to you for advice. The engineer wants to configure RIPv2 - OSPF two - way redistribution while avoiding routing loops. Which two additio ns to the router B1 configuration should the engineer make?（）

A. access - list 40 deny 172.16.1.0 0.0.0.255 access - list 40 permit any router rip redistribute ospf 100 metric 5 distribute- list 40 out ospf 100

Refer to the exhibit. R1 accesses the Internet using E0/0. You have been asked to co nfigure R1 so that a default route is generated to its downstream devices (191.0.0.1 and 192.0.0.1). Which commands would create this configuration? （）

A.router eigrp 190redistribute static ! ip route 0.0.0.0 0.0.0.0 Null0

B.ip default - network 2 0.0.0.0

C.router eigrp 190 redistribute static ! ip route 0.0.0.0 255.255.255.255 Null0

D.ip default - network 20.20.20.0
