mpls te bfd tunnel (Tunnel interface view)

Function

The mpls te bfd tunnel command sets BFD for SR-MPLS TE parameters.

The undo mpls te bfd tunnel command restores the default configuration.

By default, after BFD for SR-MPLS TE is enabled, the minimum interval at which BFD packets are sent and the minimum interval at which BFD packets are received are 10 ms, and the detection multiplier is 3.

Format

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

undo mpls te bfd tunnel { min-rx-interval [ rx-interval ] | min-tx-interval [ tx-interval ] | detect-multiplier [ multiplier ] } *

Parameters

Parameter Description Value
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.

min-tx-interval tx-interval

Specifies the minimum interval at which BFD packets are sent.

The min-tx-interval <tx-interval> parameter does not take effect in one-arm BFD for SR-MPLS TE.

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

One-arm BFD for SR-MPLS TE tunnel quickly detects faults on inter-AS E2E SR-MPLS TE tunnels and protects traffic on the E2E SR-MPLS TE tunnels. To set BFD for SR-MPLS TE parameters, run the mpls te bfd tunnel command.

Precautions

The mpls te bfd tunnel command run in the MPLS view takes effect globally and that run in the tunnel interface view takes effect only on a local interface and overwrites the BFD for SR-MPLS TE parameters configured in the MPLS view.

Example

# Set one-arm BFD for SR-MPLS TE parameters for a specified tunnel interface.
