interface to the source (the RPF interface) is VLAN-interface 20. This means that the (S, G) entry is
correct but the packet traveled along a wrong path. The packet fails the RPF check and Switch C
discards the packet.

IPv6 multicast forwarding across IPv6 unicast subnets

Routers forward the IPv6 multicast data from an IPv6 multicast source hop by hop along the forwarding
tree, but some routers might not support IPv6 multicast protocols in a network. When the IPv6 multicast
data is forwarded to a router that does not support IPv6 multicast, the forwarding path is blocked. In this
case, you can enable IPv6 multicast data forwarding across the IPv6 unicast subnets by establishing a
tunnel between the routers at both ends of the IPv6 unicast subnets.
Figure 80 IPv6 multicast data transmission through a tunnel
As shown in
Switch A encapsulates the IPv6 multicast data in unicast IPv6 packets, and forwards them to Switch B
across the tunnel through unicast routers. Then, Switch B strips off the unicast IPv6 header and continues
to forward the IPv6 multicast data down toward the receivers.

Enabling IPv6 multicast routing

Enable IPv6 multicast routing before you configure any Layer 3 IPv6 multicast functionality in the public
network or VPN instance.
