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?
A.
PE-1 must be configured with mesh-SDPs to every node receiving the multicast traffic. There is no way to reduce the replication or bandwidth.
B.
PE 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.
C.
PE-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.
D.
PE 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.
