    The term “router” in this document refers to a router in a generic sense or an S9500 series routing switch running an IPv6 multicast routing protocol. Currently, POS interfaces of S9500 series routing switches do not support IPv6 multicast. The commands to be executed in interface view are not executable in POS interface view.

    Operation Manual – IPv6 Multicast Routing and Forwarding Chapter 1 IPv6 Multicast Routing and H3C S9500 Series Routing Switches Forwarding Configuration and forwarding policy and installs the route entry into its IPv6 multicast forwarding table. 1.1.2 RPF Mechanism When creating IPv6 multicast routing table entries, an IPv6 multicast routing protocol uses the reverse path forwarding (RPF) to ensure IPv6 multicast data delivery along the correct path.
  • Page 4 Operation Manual – IPv6 Multicast Routing and Forwarding Chapter 1 IPv6 Multicast Routing and H3C S9500 Series Routing Switches Forwarding Configuration protocol does not rely on a particular type of IPv6 unicast routes; instead, it relies on the existing IPv6 unicast routing information in the device to create IPv6 multicast routing entries.

    Operation Manual – IPv6 Multicast Routing and Forwarding Chapter 1 IPv6 Multicast Routing and H3C S9500 Series Routing Switches Forwarding Configuration Figure 1-1 RPF check process When an IPv6 multicast packet arrives on VLAN-interface 1 of Switch C, as the interface is the incoming interface of the (S, G) entry, the switch forwards the packet to all outgoing interfaces.

Once an IPv6 multicast boundary is configured on an interface, this interface can no longer forward IPv6 multicast packets (including those sent from the local device) or receive IPv6 multicast packets.

  • Page 9: Troubleshooting Ipv6 Multicast Policy Configuration

    Operation Manual – IPv6 Multicast Routing and Forwarding Chapter 1 IPv6 Multicast Routing and H3C S9500 Series Routing Switches Forwarding Configuration Caution: The reset command clears the information in the IPv6 multicast routing table or the multicast forwarding table, and thus may cause transmission failure of IPv6 multicast information.
