Step Command Remarks
2. Configure the device to select
the RPF route based on the
longest prefix match.
multicast longest-match
By default, the route with the
highest priority is selected as the
RPF route.
Configuring multicast load splitting
To optimize the traffic delivery for multiple data flows, you can configure load sharing on a per-source
basis or on a per-source-and-group basis.
To configure multicast load splitting:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Configure multicast load
splitting.
multicast load-splitting { source |
source-group }
By default, load splitting is
disabled.
Configuring a multicast forwarding boundary
A multicast forwarding boundary sets the boundary condition for the multicast groups in a specified
range. The multicast data for a multicast group travels within a definite boundary in a network. If the
destination address of a multicast packet matches the boundary condition, the packet is not forwarded.
If an interface is configured as a multicast boundary, it can no longer forward multicast packets
(including packets sent from the local device), nor receive multicast packets.
To configure a multicast forwarding boundary:

3. Configure a multicast
forwarding boundary.

By default, no forwarding
boundary is configured.
Configuring static multicast MAC address entries
In Layer 2 multicast, multicast MAC address entries can be dynamically created or added through Layer
2 multicast protocols (such as IGMP snooping). You can also manually configure static multicast MAC
address entries to bind multicast MAC addresses and ports to control the destination ports of the multicast
data.
When you configure static multicast MAC address entries, follow these guidelines:
