Step 4 (Optional) Run:
multicast ipv6 load-splitting weight weight-value
The interface is configured with an IPv6 multicast load splitting weight.
By default, the IPv6 multicast load splitting weight of an interface is 1.
The greater the load splitting weight of an interface, the more IPv6 multicast routing entries with
this interface being the upstream interface. When the IPv6 multicast load splitting weight on an
interface is 0, it indicates that the routes with this interface being the upstream interface do not
take part in load splitting.

14.3.3 Configuring an IPv6 Multicast Load Splitting Weight

When an IPv6 multicast load splitting policy is configured, because the forwarding capabilities
of equal-cost routes are different from the actual load bearing situation on the equal-cost routes,
balanced load splitting cannot meet network requirements in some scenarios. In such a case, you
can configure a load splitting weight on an interface to achieve unbalanced multicast load
splitting.
Context
When stable-preferred or balance-preferred load splitting is configured, because the forwarding
capabilities of equal-cost routes are different from the actual load bearing situation on the equal-
cost routes, balanced load splitting cannot meet network requirements in some scenarios. In such
a case, you can configure an IPv6 multicast load splitting weight on an interface to achieve
unbalanced multicast load splitting.
Do as follows on the switch enabled with IPv6 multicast:

applicable to the scenario of multiple sources to multiple groups.
NOTE
It is recommended to adopt a fixed IPv6 multicast load splitting policy based on the actual networking.
The balance-preferred or stable-preferred policy is preferred.
balance-preferred or stable-preferred cannot be configured on the interface enabled with PIM-DM.
You can configure a multicast load splitting weight only in a stable-preferred load splitting or balance-
preferred load splitting scenario.
