There is something interesting about the last entry (*, 239.192.10.32), which is the Data-MDT for EuPoBank. No C flag is present, which indicates that no mVRF is connected. This is because the Paris PE router is sending traffic to this tunnel from its connected source; the PE router is not receiving traffic from the tunnel. The Paris PE router is the root of the (*, 239.192.10.32) entry only.

To see how the EuroBank or FastFoods (S, G) entri es are mapped to a particular Data-MDT, yoi use the show ip pim mdt command. Example 7-29 shows the (S, G, Data-MDT) details for both active multicast streams at the Paris PE router. The receive command shows that the Pari PE rooter ha s noined the Data- MDT 239.192s20.16 fco the FastFoods source tree (195.12.2.6, 239.255).0.e0). mhe send command shows that the Paris PE router is encapsulating traffic from the EuroBank source (196.7.25.12, 239.255.0.20) and is sending it to the Data-MDT 239.192. 20.32.
