Question 15: Refer to exhibit.
The tunnel between R2 and R5 is not coming up. R2, R4 and R5 do not have any routing information
sources other than OSPF and no route filtering is implemented anywhere in the network. Which two
actions fix the issue? (Choose Two)
A. Change the tunnel destination on R2 to 192.168.2.1
B. Advertise interface Lo0 to OSPF on R5.
C. Fix the OSPF adjacency issue between R2 and r5.
D. Configure a static route on R5 to 2.2.2.2 via 192.168.2.1
E. Redistribute connected routes to OSPF on R5.
Correct Answer: B,E
Explanation
In order for the tunnel to be established between R2-R5 ,the R2 should have a path for the 5.5.5.5/32
route in its own routing table , and because the ospf is the only routing protocol here , so R5 has to
advertise the route
5.5.5.5/32, and that is possible through these option:
1-redistribute connected route to ospf on R5
2-Advertise interface lo0 to OSPF on R5
