mpls te bfd (Tunnel interface view)

Format

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

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

Parameters

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.

Parameter

Description

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 Guidelines

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.

Example

# Configure parameters of a BFD session detecting faults in a specified TE LSP.
