Configuration Task List; Enabling Ip Multicast Routing - HPE FlexNetwork 5510 HI Series Configuration Manual

Figure 28 Multicast data transmission through a tunnel
Multicast device
Source
As shown in
Device A encapsulates the multicast data in unicast IP packets, and forwards them to Device B
across the tunnel through unicast routers. Then, Device B strips off the unicast IP header and
continues to forward the multicast data to the receiver.
To use this tunnel only for multicast traffic, configure the tunnel as the outgoing interface only for
multicast routes.
