multicast unicast-reservable-bandwidth
Function
The multicast unicast-reservable-bandwidth command configures the minimum bandwidth reserved for unicast and enable multicast virtual scheduling.
The undo multicast unicast-reservable-bandwidth command cancels the minimum bandwidth reserved for unicast and disable multicast virtual scheduling.
By default, the minimum bandwidth reserved for unicast is not configured.
This command is supported only on the NetEngine 8000 F1A.
Parameters
| Parameter | Description | Value |
|---|---|---|
| pir pir-value |
Specifies the peak rate of traffic. The peak rate refers to the maximum traffic rate that is allowed. |
The value is an integer ranging from 128 to 1000000, in kbit/s. In addition, pir-value should be no less than the configured cir-value. |
| coexist-with |
Specifies multicast virtual scheduling is enabled when session-based multicast replication function is enabled on the BAS interface. |
- |
| copy-by-session |
Specifies session-based multicast replication function. |
- |
| cir cir-value |
Specifies the average rate of traffic. |
The value is an integer ranging from 128 to 1000000, in kbit/s. |
Usage Guidelines
Usage Scenario
The multicast virtual scheduling is valid after multicast unicast-reservable-bandwidth is run. Actually, this command is a switch for enabling or disabling the multicast virtual scheduling.
Prerequisites
Generally, the Router replicates only one copy of multicast traffic of a multicast group to each physical interface. Then the Layer 2 device replicates the multicast traffic to each member in the multicast group. If the Layer 2 device does not provide IGMP/MLD snooping for user identification, run the multicast copy by-session command to enable session-based multicast replication on the BAS interface of the Router. After the configuration is complete, the Router directly copies multicast traffic to each user.
