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 configuration.
By default, no parameter of a BFD session for RSVP on a specified interface is set.

Parameter |
Description |
Value |
|---|---|---|
min-tx-interval tx-interval |
Specifies the interval at which BFD packets are sent. |
The value ranges from 100 to 1000, in milliseconds. By default, the value is 1000. After the set service-mode enhanced command is configured on the S5720-HI, S5731-H, S5731S-H, S5730-HI, and S6720-HI, the value ranges from 3 to 1000. After the set service-mode enhanced-bfd command is configured on the S5732-H, S6730S-H, and S6730-H, the value ranges from 3 to 1000. |
min-rx-interval rx-interval |
Specifies the interval at which BFD packets are received. |
The value ranges from 100 to 1000, in milliseconds. By default, the value is 1000. After the set service-mode enhanced command is configured on the S5720-HI, S5731-H, S5731S-H, S5730-HI, and S6720-HI, the value ranges from 3 to 1000. After the set service-mode enhanced-bfd command is configured on the S5732-H, S6730S-H, and S6730-H, the value ranges from 3 to 1000. |
detect-multiplier multiplier |
Specifies the local detection multiplier value of a BFD session. |
An integer ranging from 3 to 50. The value is 3 by default. |

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.
Then,
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).
