By default, the multicast load splitting weight of an interface is 1.
The greater the multicast load splitting weight of an interface, the more multicast
routing entries with this interface being the upstream interface. When the 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.

9.4.4 Configuring a Multicast Load Splitting Weight
When a 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 a load splitting weight on an interface to achieve unbalanced multicast
load splitting.
Do as follows on the switch enabled with multicast:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface interface-type interface-number
The interface view is displayed.
The interface can be a VLANIF interface, or an Loopback interface.
By default, the multicast load splitting weight of an interface is 1.
The greater the multicast load splitting weight of an interface, the more multicast routing entries
with this interface being the upstream interface. When the 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.
Step 3 Run:
multicast load-splitting weight weight-value
The multicast load splitting weight is set on the interface.
----End
9.4.5 Checking the Configuration
After multicast routing policies are configured, you can check the multicast routing table and
RPF routing information to ensure normal running of the multicast network.
