The system view is displayed.
Step 2 Run:
interface vlanif interface-number
The interface view is displayed.
Step 3 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.

14.3.4 Checking the Configuration
After IPv6 multicast routing policies are configured, you can check information about the IPv6
multicast routing table and RPF routing information of a specified multicast source to ensure
normal running of the multicast network.
Procedure
l Run the display multicast ipv6 routing-table [ ipv6-source-address [ ipv6-source-mask-
length ] | ipv6-group-address [ ipv6-group-mask-length ] | incoming-interface { interface-
type interface-number | register } | outgoing-interface { { exclude | include | match }
{ interface-type interface-number | register | none } } ]
*
[ outgoing-interface-number
[ number ] ] command to check the IPv6 multicast routing table.
l Run the display multicast ipv6 rpf-info ipv6-source-address [ ipv6-group-address ]
[ rpt | spt ] command to display the IPv6 RPF routing information of a source-specific
multicast group.
----End
14.4 Limiting the Range of Multicast Forwarding
Multicast information of each multicast group in a network should be transmitted within a certain
scope. Therefore, configuring an IPv6 multicast forwarding boundary, setting the TTL threshold
of IPv6 multicast forwarding, and disabling an interface from receiving IPv6 multicast packets
are necessary for restricting the multicast data forwarding scope.
14.4.1 Establishing the Configuration Task
Before configuring the IPv6 multicast data forwarding scope, familiarize yourself with the
applicable environment, pre-configuration tasks, and required data. This can help you complete
the configuration task quickly and accurately.
