Exam 300-410 topic 1 question 247 discussion

Actual exam question from Cisco's 300-410

Question #: 247
Topic #: 1

Refer to the exhibit. An engineer must redistribute networks 192.168.10.0/24 and 192.168.20.0/24 into OSPF from EIGRP, where the metric must be added when traversing through multiple hops to start an external route of 20. The engineer notices that the external metric is fixed and does not add at each hop. Which configuration resolves the issue?

A. R2(config)#access-list 10 permit 192.168.10.0 0.0.0.255 R2(config)#access-list 10 permit 192.168.20.0 0.0.0.255 ! R2(config)#route-map RD permit 10 R2(config-route-map)#match ip address 10 R2(config-route-map)#set metric 20 R2(config-route-map)#set metric-type type-2 ! R2(config)#router ospf 10 R2(confjg-router)#redistribute eigrp 10 subnets route-map RD
B. R2(config)#access-list 10 permit 192.168.10.0 0.0.0.255 R2(config)#access-list 10 permit 192.168.20.0 0.0.0.255 ! R2(config)#route-map RD permit 10 R2(config-route-map)#match ip address 10 R2(config-route-map)#set metric 20 R2(config-route-map)#set metric-type type-1 ! R2(config)#router ospf 10 R2(config-router)#redistribute eigrp 10 subnets route-map RD
C. R1(config)#access-list 10 permit 192.168.10.0 0.0.0.255 R1(config)#access-list 10 permit 192.168.20.0 0.0.0.255 ! R1(config)#route-map RD permit 10 R1(config-route-map)#match ip address 10 R1(config-route-map)#set metric 20 R1(config-route-map)#set metric-type type-1 ! R1(config)#router ospf 10 R1(config-router)#redistribute eigrp 10 subnets route-map RD
D. R1(config)#access-list 10 permit 192.168.10.0 0.0.0.255 R1(config)#access-list 10 permit 192.168.20.0 0.0.0.255 ! R1(config)#route-map RD permit 10 R1(config-route-map)#match ip address 10 R1(config-route-map)#set metric 20 R1(config-route-map)#set metric-type type-2 ! R1(config)#router ospf 10 R1(config-router)#redistribute eigrp 10 subnets route-map RD

Given answer is correct. Only external type1 routes will provide the hop count, as it traverses through the network.

B is correct If routes are redistributed into OSPF as type 1, then the cost to reach the external networks could vary from router to router. If routes are redistributed into OSPF as type 2, then every router in the OSPF domain will see the same cost to reach the external networks. https://community.cisco.com/t5/routers-small-business/metric-type-in-ospf/td-p/2624188#:~:text=If%20routes%20are,router%20to%20router.

Selected Answer: B

The router connecting OSPF and EIGRP domains by redistribution is an ASBR, in this case it is R2. The configuration needs to be applied there. => Answer "B".
