Configuring the RPF route selection rule You can configure the router to select the RPF route based on the longest prefix match principle. For more information about RPF route selection, see "RPF check process." To configure a multicast routing policy: Step 1. Enter system view. 2. Configure the device to select the RPF route based on the longest prefix match. Command system-view multicast longest-match Remarks N/A 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 splitting on a per-source basis or on a per-source-and-group basis. To configure multicast load splitting: Step 1. Enter system view. 2. Configure multicast load splitting. Command system-view multicast load-splitting { source | source-group } Remarks N/A 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: Step 1. Enter system view. 2. Enter interface view. 3. Configure a multicast forwarding boundary. Command system-view interface interface-type interface-number multicast boundary group-address { mask-length | mask } Remarks N/A N/A 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 38

Configuring the RPF route selection rule
You can configure the router to select the RPF route based on the longest prefix match principle. For more
information about RPF route selection, see "
RPF check process
."
To configure a multicast routing policy:
Step
Command
Remarks
1.
Enter system view.
system-view
N/A
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 splitting 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:
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
