Huawei quidway s7700 - Configuring Ipv6 Multicast Load Splitting

No. Data
1 IPv6 load splitting policy
2 IPv6 load splitting weight on the interface
14.3.2 Configuring IPv6 Multicast Load Splitting
The multicast load splitting function extends multicast routing rules, which does not fully depend
on the RPF check. Performing load splitting of multicast traffic according to different policies
can optimize network traffic transmission in the scenario where multiple multicast data flows
exist. You can choose to configure a balance-preferred or stable-preferred load splitting policy.
Context
The IPv6 multicast load splitting function extends multicast routing rules, which does not fully
depend on the RPF check. If multiple equal-cost optimal routes exist over the network, they all
can be used for multicast data forwarding. In the case that the multicast service is guaranteed,
multicast traffic is load split to multiple equal-cost routes.
By default, IPv6 multicast load splitting is not configured.
Do as follows on the switch enabled with IPv6 multicast:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
multicast ipv6 load-splitting { balance-preferred | stable-preferred | source |
group | source-group }
IPv6 multicast splitting is configured.
Parameters in the command are described as follows:
l balance-preferred: indicates balance-preferred load splitting. This policy is applicable to
the scenario where hosts frequently join or leave the groups, which requires automatic load
adjustment.
If balance-preferred is specified, the switch automatically adjusts and balances the entries
on the equal-cost routes when equal-cost routes are added or deleted, IPv6 multicast routing
entries are deleted, or IPv6 load splitting weights on the interfaces are changed.
l stable-preferred: indicates stable-preferred load splitting. This policy is applicable to the
stable multicast networking.
If stable-preferred is specified, the switch automatically adjusts and balances the entries
when equal-cost routes are added or deleted; however, when IPv6 multicast routing entries
are deleted or IPv6 load splitting weights on the interfaces are changed, the switch does not
automatically adjust the entries on the equal-cost routes.
