Step Command 2. Enable IPv6 multicast routing. multicast ipv6 routing-enable Remarks Disabled by default. Configuring IPv6 multicast routing and forwarding Before you configure IPv6 multicast routing and forwarding, complete the following tasks: • Enable IPv6 forwarding and configure an IPv6 unicast routing protocol so that all devices in the domain are interoperable at the network layer. • Configure IPv6 PIM-DM or IPv6 PIM-SM. • Determine the maximum number of downstream nodes for a single entry in the IPv6 multicast forwarding table. • Determine the maximum number of entries in the IPv6 multicast forwarding table. Configuring an IPv6 multicast routing policy You can configure the router to determine the RPF route based on the longest match principle. For more information about RPF route selection, see "RPF check mechanism." By configuring per-source or per-source-and-group load splitting, you can optimize the traffic delivery when multiple IPv6 multicast data streams are handled. To configure an IPv6 multicast routing policy: Step 1. Enter system view. Command system-view 2. Configure the device to select the RPF route based on the multicast ipv6 longest-match longest match. 3. Configure IPv6 multicast load multicast ipv6 load-splitting splitting. {source | source-group } Remarks N/A Optional. The route with the highest priority is selected as the RPF route by default. Optional. Disabled by default. Configuring an IPv6 multicast forwarding range IPv6 multicast packets do not travel infinitely in a network. The IPv6 multicast data of each IPv6 multicast group must be transmitted within a definite scope. You can configure the forwarding boundary for a specific IPv6 multicast group or an IPv6 multicast group with the scope field in its group address being specified on all interfaces that support IPv6 multicast forwarding. A multicast forwarding boundary sets the boundary condition for the IPv6 multicast groups in the specified range or scope. If the destination address of an IPv6 multicast packet matches the set boundary condition, the packet will not be forwarded. 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. To configure an IPv6 multicast forwarding range: 254
