Scenario:
A customer network engineer has edited their OSPF network configuration and now your customer
is experiencing network issues. They have contacted you to resolve the issues and return the
network to full functionality.
Connectivity from R3 to R4, R5 and R6 has been lost. How should connectivity be reestablished?
A.
Configure R4 with a virtual link to 192.168.13.2
B.
Change the R3 and R4 hello-interval and retransmit-interface timers to zero so the link won’t go
down.
C.
Add an OSPF network statement for 4.4.4.4 0.0.0.0 area 1 in R3
D.
Add an OSPF network statement for 192.168.34.3 0.0.0.255 area 2 in R3
E.
Add an OSPF network statement for 192.168.34.0 0.0.0.255 area 1 in R3
Explanation:
Based on the network diagram, we know that a virtual link will need to be configured to logically
connect area 2 to the back area 0. However, this is not the problem as we can see that R3 has
been correctly configured to do this. It is, however, missing the network statement for the link to R4.
Here, we see that the link to R4 is using the 192.168.34.0 network, but that this network has not
been added to OSPF
Based on the network diagram, this link should be added to Area 1, not Area 2.
