Before configuring IPv6 multicast routing and forwarding, complete the following tasks:  

z 

Configure an IPv6 unicast routing protocol so that all devices in the domain are interoperable at the 

network layer. 

z 

Configure IPv6 PIM-DM or IPv6 PIM-SM. 

Before configuring IPv6 multicast routing and forwarding, prepare the following data:  

z 

Maximum number of downstream nodes for a single entry in the IPv6 multicast forwarding table  

z 

Maximum number of entries in the IPv6 multicast forwarding table 

You can configure the router to determine the RPF route based on the longest match principle. For 

details about RPF route selection, refer to 

.  

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.  

Follow these steps to configure an IPv6 multicast routing policy:  

Enter system view 

— 

Configure the device to select 
the RPF route based on the 
longest match 

Optional 

The route with the highest 
priority is selected as the RPF 
route by default 

Configure IPv6 multicast load 
splitting 

multicast ipv6 load-splitting 
{source | source-group } 

Optional 

Disabled by default  

 

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. Presently, you can define an IPv6 multicast 

forwarding range by: Specifying boundary interfaces, which form a closed IPv6 multicast forwarding 

area. 

You can configure the forwarding boundary for a specific IPv6 multicast group 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. 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.
