Question #: 4
Topic #: 3

Scenario:
You have been asked by your customer to help resolve issues in their routed network. Their network engineer has deployed HSRP. On closer inspection HSRP doesn't appear to be operating properly and it appears there are other network problems as well. You are to provide solutions to all the network problems.

You examine the configuration on R5 and discover that no routes are being learned from R4. Which issue prevents the route entries from being installed in the routing table?

A. HSRP issue between R5 and R4
B. There is an OSPF issue between R5and R4
C. There is a DHCP issue between R5 and R4
D. The distribute-list configured on R5 is blocking route entries
E. The ACL configured on R5 is blocking traffic for the subnets advertised from R4.

Show Suggested Answer

Suggested Answer: B 🗳️
If we issue the "show ip route" and "show ip ospf neighbor" commands on R5, we see that there are no learned OSPF routes and he has no OSPF neighbors.

Absence of neighbour not necessary caused by OSPF issues. It may be interface of address issues. For example, lack of ip address due to dhcp misconfiguration. So we need check interfaces statuses and configurations on both routers.
