The micro-isolation protocol-car ospf command sets OSPF micro-isolation CAR parameters.
The undo micro-isolation protocol-car ospf command restores the default CAR parameter values for OSPF micro-isolation.
By default, OSPF uses the default micro-isolation CAR parameters.
| Parameter | Description | Value |
|---|---|---|
| cir cir-value |
Specifies the committed information rate (the average rate at which packets can be transmitted or forwarded). |
The value ranges from 0 to 1000000, in kbit/s. The default value is 8. |
| cbs cbs-value |
Specifies the committed burst size (size of the the committed burst traffic that can instantaneously pass through). |
The value ranges from 0 to 1000000, in bytes. The default value is 100000. |
| pir pir-value |
Specifies the PIR (the highest rate at which packets can be transmitted or forwarded). |
The value ranges from 0 to 1000000, in kbit/s. The default value is 16000. |
| pbs pbs-value |
Specifies the peak burst size (peak burst traffic that can instantaneously pass through). |
The value ranges from 0 to 10000000, in bytes. The default value is 9000000. |
Usage Scenario
When OSPF packets flood, you can run this command to adjust the interface- and destination IP address-based packet channel bandwidth in OSPF micro-isolation CAR to ensure that OSPF packets can be sent properly.
Precautions
In normal cases, you are not advised to adjust OSPF micro-isolation CAR parameters. Use the default value for this parameter instead.
The PIR must be greater than or equal to the CIR, and the PBS must be greater than or equal to the CBS.
