The mpls rsvp-te bfd command sets parameters of a BFD session for RSVP on a specified interface.
The undo mpls rsvp-te bfd command restores the default BFD parameters.
By default, BFD sessions use default parameter values.
| Parameter | Description | Value |
|---|---|---|
| detect-multiplier multiplier |
Specifies a BFD detection multiplier. |
The value is an integer that ranges from 3 to 50. The default value is 3. |
| min-tx-interval tx-interval |
Specifies the minimum interval at which BFD packets are sent. |
The value is an integer that ranges from 3 to 20000. The default value is 10. |
| min-rx-interval rx-interval |
Specifies the minimum interval at which BFD packets are received. |
The value is an integer that ranges from 3 to 20000. The default value is 10. |
| process-pst |
Set BFD PST. |
- |
| tos-exp tosexp-value |
Configure the priority of BFD packets. |
An integer ranging from 0 to 7. |

Usage Scenario
To set parameters of a BFD session for RSVP on a specified interface, run the mpls rsvp-te bfd command.
Actual local interval at which BFD packets are sent = MAX { Local interval at which BFD packets are sent, Remote interval at which BFD packets are received }; Actual local interval at which BFD packets are received = MAX { Remote interval at which BFD packets are sent, Local interval at which BFD packets are received }; Local detection period = Actual interval at which BFD packets are received x Remote BFD detection multiplier. For example: The local sending interval is 200 ms, while the local receiving interval is 300 ms, and the detection multiplier is 4. The remote sending interval is 100 ms, while the remote receiving interval is 600 ms, and the detection multiplier is 5. The actual local sending interval is 600 ms (MAX { 200 ms, 600 ms }), while the local receiving interval is 300 ms (MAX { 100 ms, 300 ms }), and the detection period is 1500 ms (300 ms x 5). The actual remote sending interval is 300 ms (MAX { 100 ms, 300 ms }), while the receiving interval is 600 ms (MAX { 200 ms, 600 ms }), and the detection period is 2400 ms (600 ms x 4). On an interface on which BFD for PST is enabled, configure the process-pst parameter in this command to enable the interface to more rapidly obtain BFD detection results.Prerequisites
