The mpls te bfd command sets parameters of a BFD session detecting faults in a TE LSP.
The undo mpls te bfd command restores the default BFD parameters.
By default, the min-tx-interval is 10 milliseconds, the min-rx-interval is 10 milliseconds, and the Detect-multiplier is 3.
| Parameter | Description | Value |
|---|---|---|
| min-tx-interval tx-interval |
Specifies the minimum interval at which BFD packets are sent. |
The value is an integer ranging from 3 to 20000, in milliseconds. |
| min-rx-interval rx-interval |
Specifies the minimum interval at which BFD packets are received. |
The value is an integer ranging from 3 to 20000, in milliseconds. |
| detect-multiplier multiplier |
Specifies a BFD detection multiplier. |
The value is an integer ranging from 3 to 50. |
Usage Scenario
If min-tx-interval tx-interval configured locally is different from min-rx-interval rx-interval configured remotely, a larger value between these two values takes effect.
detect-multiplier multiplier configured remotely takes effect on both ends of a BFD session. The mpls te bfd command run in the MPLS view takes effect globally; The mpls te bfd command run in the tunnel interface view takes effect only on the interface. BFD for TE LSP parameters set in tunnel interface view override those set in the MPLS view.
