Question #: 80
Topic #: 7

Click on the exhibit below.

Assume PE-1 has a mesh-sdp configured to every PE node in both Metro networks. What could be done to prevent the bandwidth replication between Metro 1 and Metro 2?

APE-1 must be configured with mesh-SDPs to every node receiving the multicast traffic. There is no way to reduce the replication or bandwidth.

BPE nodes in Metro 1 could be configured with mesh-SDPs. PE nodes in Metro 2 would be configured with mesh-SDPs. However, the connection between Metro networks (PE-2 to PE-6) can be configured with a spoke-sdp. This would reduce the replication and bandwidth used on the link between Metro networks. This also reduces the replication required by PE-1.

CPE-1 can be configured with spoke-SDPs to every PE node in both Metro networks. This will reduce the bandwidth and replication within the network.

DPE nodes in Metro 1 could be configured with spoke-SDPs. PE nodes in Metro 2 would be configured with spoke-SDPs. However, the connection between Metro networks (PE-2 to PE-6) can be configured with a mesh-sdp. This would reduce the replication and bandwidth used on the link between Metro networks. This also reduces the replication required by PE-1.

Hold on, did you see the part about the mesh-SDPs? That's a lot of config work. I'm leaning towards Option C, where PE-1 can just use spoke-SDPs to cut down on the hassle.

I'm not sure about this. Option C also seems like a valid choice to reduce bandwidth and replication. Configuring PE-1 with spoke-SDPs to every PE node in both Metro networks could be a simpler solution.

I agree with you, Terina. Using a combination of mesh-SDPs and spoke-SDPs can help reduce replication and bandwidth usage. It's important to optimize the network for efficiency.

Okay, let's think this through. Option B seems to be the most comprehensive solution, reducing the replication and bandwidth between the metro networks.

I think the answer is B. Configuring PE nodes in Metro 1 and Metro 2 with mesh-SDPs and using spoke-SDPs for the connection between Metro networks seems like the best way to prevent bandwidth replication.

I'm not sure, but option D also sounds reasonable. It proposes using spoke-SDPs in Metro 1 and Metro 2, and a mesh-sdp between them to reduce replication and bandwidth. It's a tough choice.

I agree with Lavelle. Option B seems to provide a good balance between reducing replication and bandwidth while maintaining connectivity between the Metro networks.

I think option B is the best choice. It suggests configuring mesh-SDPs in Metro 1 and Metro 2, and spoke-SDPs between them to reduce replication and bandwidth.
