Cisco 300-510 Exam - Topic 10 Question 116 Discussion

Refer to the exhibit.A network engineer at a large ISP with an employee ID 4876 94 052 started to configure OSPF on two routers The engineer notices that router 1 learned about network 20 20 20 0/24 from router 2, but router 2 did not learn about 10.10 10.0/24 from router 1 Layer 2 and Layer 3 connectivity are working between the two routers and the physical connection between the devices is functioning. Which action must the engineer take to resolve the issue?
A) Replace the router 1 OSPF network configuration with network 10.10.10.0 0.0.0.255 area 0.
B) On router 1 configure a route map with a distribution list for the 10 10.10 0/24 network.
C) Replace the router 2 OSPF network configuration with network 10.10.10.0 0.0.0.255 area
D) On router 2 configure a route map with a distribution list for the 101010 0/24 network

I’m not sure. All options seem valid, but A feels most straightforward.

Wait, why isn't router 2 learning from router 1? That seems odd.

B is the way to go. Routing issues can be tricky, but a route map should do the trick.

I agree, B is the correct answer. The engineer needs to configure a route map on router 1 to advertise the 10.10.10.0/24 network.

Option B seems like the right choice here. Configuring a route map with a distribution list for the 10.10.10.0/24 network on router 1 should resolve the issue.

I feel like I should choose option A, but I can't recall if it’s better to adjust router 2 instead.

This kind of question came up in our practice exam! I think it might be related to how the networks are defined in OSPF.

I remember something about OSPF network statements needing to match for routes to be exchanged, but I'm not sure which router to change.

I'm feeling pretty confident about this one. The issue is clearly with the OSPF network configuration on one of the routers. I'll start by reviewing the configurations on both routers and then decide which option is the best solution.

Okay, I think I've got this. The key is that router 1 is learning the 20.20.20.0/24 network from router 2, but router 2 isn't learning the 10.10.10.0/24 network from router 1. I'll try option B and configure a route map with a distribution list on router 1.

This looks like a tricky OSPF configuration issue. I'll need to carefully review the network details and the options to determine the best approach.
