bfd (SRv6 TE policy view)

Function

The bfd command configures BFD(Bidirectional Forwarding Detection) parameters for an SRv6 TE Policy.

The undo bfd command deletes BFD parameters configured for an SRv6 TE Policy.

The bfd backup-path command configures BFD parameters for the backup path of an SRv6 TE Policy.

The undo bfd backup-path command deletes BFD parameters configured for the backup path of an SRv6 TE Policy.

By default, the srv6-te-policy bfd detect-multiplier min-tx-interval command configuration is directly inherited.

Format

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

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

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

undo 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 that ranges from 3 to 20000, in milliseconds.
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 that ranges from 3 to 20000.
detect-multiplier detectmulti-value	Specifies a local detection multiplier.	The value is an integer that ranges from 3 to 50.
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.

Usage Guidelines

Usage Scenario

You can run the srv6-te-policy bfd detect-multiplier min-tx-interval command in the SRv6 view to configure BFD parameters for all SRv6 TE Policies. The bfd detect-multiplier min-tx-interval command run in the SRv6 TE Policy view can be used to set BFD parameters for a single SRv6 TE Policy.

For the same SRv6 TE Policy, if both the bfd detect-multiplier min-tx-interval (SRv6 view) and bfd detect-multiplier min-tx-interval (SRv6 TE Policy view) commands are run, the bfd detect-multiplier min-tx-interval (SRv6 TE Policy view) command takes precedence over the bfd detect-multiplier min-tx-interval (SRv6 TE Policy view) command.

You can run the srv6-te-policy bfd detect-multiplier min-tx-interval backup-path command in the SRv6 view to configure BFD parameters for the backup paths of all SRv6 TE Policies. You can run the bfd detect-multiplier min-tx-interval backup-path command in the SRv6 TE Policy view to configure BFD parameters for the backup path of a single SRv6 TE Policy.

If the bfd detect-multiplier min-tx-interval backup-path (SRv6 TE Policy view) command is run for an SRv6 TE Policy, BFD parameters for the backup path of the SRv6 TE Policy take effect. If this command is not run but the srv6-te-policy bfd detect-multiplier min-tx-interval backup-path (SRv6 view) command is run, the srv6-te-policy bfd detect-multiplier min-tx-interval backup-path (SRv6 view) command takes effect. If neither of the preceding commands is configured and the bfd detect-multiplier min-tx-interval (SRv6 TE Policy view) command is configured, the bfd detect-multiplier min-tx-interval (SRv6 TE Policy view) command takes effect. If neither of the preceding commands is configured, the srv6-te-policy bfd detect-multiplier min-tx-interval (SRv6 view) command takes effect.
