The micro-isolation protocol-car bgp command sets parameters of micro-isolation CAR for BGP messages used to establish peer relationships.
The undo micro-isolation protocol-car bgp command restores the default parameters of micro-isolation CAR for BGP messages used to establish peer relationships.
By default, the CIR, CBS, PIR, and PBS of micro-isolation CAR for BGP messages are 24 kbit/s, 15000 bytes, 48000 kbit/s, and 6000000 bytes, respectively.
| Parameter | Description | Value |
|---|---|---|
| cir cir-value |
Specifies a committed information rate (CIR), that is, the average rate at which packets can be transmitted or forwarded. |
The value ranges from 12 to 1200, in kbit/s. The default value is 24. |
| cbs cbs-value |
Specifies a committed burst size (CBS), which limits the maximum number of bytes available for a burst of packets in a short interval to remain within CIR. |
The value ranges from 15000 to 1500000, in bytes. The default value is 15000. |
| pir pir-value |
Specifies a peak information rate (PIR), that is, the peak rate at which packets can be transmitted or forwarded. |
The value ranges from 12000 to 60000, in kbit/s. The default value is 48000. |
| pbs pbs-value |
Specifies a peak burst size (PBS), which limits the maximum number of bytes available for a burst of packets in a short interval to remain within PIR. |
The value is in the range of 1500000-7500000, in bytes. The default value is 6000000. |
Usage Scenario
When BGP messages used to establish peer relationships suffer a traffic burst, their bandwidth may be preempted by non-BGP protocol packets. To adjust the parameters of micro-isolation protocol-car for BGP messages used to establish peer relationships, run the micro-isolation protocol-car bgp command. This ensures that BGP messages used to establish peer relationships on each interface and sub-interface are sent properly.
