2. Enter MRIB view.

3. Configure multicast load
splitting.
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 specific 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.
TIP:
You do not need to enable IP multicast routing before this configuration.
To configure a multicast forwarding boundary:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Configure a multicast
forwarding boundary. multicast boundary group-address
{ mask-length | mask } 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.
TIP:
•
You do not need to enable IP multicast routing before this configuration.
• The multicast MAC address that can be manually configured in a multicast MAC address entry must be
unused. A multicast MAC address is the MAC address in which the least significant bit of the most
significant octet is 1.
You can configure static multicast MAC address entries on the specified interface in system view, or on
the current interface in interface view.
To configure a static multicast MAC address entry in system view:
Step Command Remarks
1. Enter system view. system-view N/A
