srv6-te-policy bfd (Segment routing IPv6 view)

Function

The srv6-te-policy bfd command configures seamless bidirectional forwarding detection (BFD) parameters for SRv6 TE Policies.

The undo srv6-te-policy bfd command deletes configured BFD parameters.The srv6-te-policy bfd backup-path command configures seamless BFD parameters for the backup path of all SRv6 TE Policies.The undo srv6-te-policy bfd command deletes BFD parameters configured for the backup path of all SRv6 TE Policies.

By default, the minimum interval for sending SBFD packets for an SRv6 TE Policy is 10 ms, and the local detection multiplier is 3.

Format

srv6-te-policy bfd { min-tx-interval tx-value | detect-multiplier detectmulti-value } ^*

srv6-te-policy bfd { min-tx-interval backup-tx-value | detect-multiplier backup-detectmulti-value } ^* backup-path

undo srv6-te-policy bfd { min-tx-interval [ tx-value ] | detect-multiplier [ detectmulti-value ] } ^*

undo srv6-te-policy bfd { min-tx-interval [ backup-tx-value ] | detect-multiplier [ backup-detectmulti-value ] } ^* backup-path

Parameters

Parameter	Description	Value
min-tx-interval tx-value	Specifies the minimum interval for sending BFD packets to the peer end.	The value is an integer ranging from 3 to 20000, in milliseconds. The default value is 10.
min-tx-interval backup-tx-value	Specifies the minimum interval at which BFD packets are sent over the backup path of an SRv6 TE Policy.	The value is an integer ranging from 3 to 20000.
detect-multiplier backup-detectmulti-value	Specifies a local detection multiplier for the backup path of an SRv6 TE Policy.	The value is an integer that ranges from 3 to 50.
detect-multiplier detectmulti-value	Specifies the local detection multiplier.	The value is an integer that ranges from 3 to 50. The default value is 3.

Usage Guidelines

Usage Scenario

The srv6-te-policy bfd command adjusts BFD parameters of an SRv6 TE Policy to meet different network requirements.

Precautions

If you run the srv6-te-policy bfd command, the bfd, and srv6-te-policy bfd enable commands must also be run. Otherwise, the srv6-te-policy bfd command cannot take effect.

Example

# Set the minimum interval at which BFD packets are sent to 300 ms for an SRv6 TE Policy.
