bfd (MPLS TE P2P template view)

Function

The bfd command sets BFD for CR-LSP parameters.

By default, the minimum interval at which BFD packets are sent is 10 ms, the minimum interval at which BFD packets are received is 10 ms, and the local detection multiplier is 3.

Format

bfd { min-tx-interval min-tx-interval | min-rx-interval min-rx-interval | detect-multiplier multiplier } ^*

undo bfd { min-tx-interval | min-rx-interval | detect-multiplier } ^*

Parameters

Parameter	Description	Value
min-tx-interval min-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 min-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 Guidelines

Usage Scenario

To set BFD parameters, run the bfd command. The parameters include the minimum interval at which BFD packets are sent, the minimum interval at which BFD packets are received, and the BFD detection multiplier.

Effective local interval at which BFD packets are sent = MAX { Locally configured interval at which BFD packets are sent, Remotely configured interval at which BFD packets are received }
Effective local interval at which BFD packets are received = MAX { Remotely configured interval at which BFD packets are sent, Locally configured interval at which BFD packets are received }
Local BFD detection period = Effective local interval at which BFD packets are received x Remotely configured BFD detection multiplier
The detection multiplier is the maximum number of BFD packets dropped before a BFD peer is declared Down.

Example

# Set the minimum interval at which BFD packets are sent to 200 milliseconds.
