Purpose
Enters global configuration mode.
Enters MPLS-TE configuration mode.
Enables soft-preemption on a node.
If soft-preemption is enabled, the head-end node tracks
Note
whether an LSP desires the soft-preemption treatment.
However, when a soft-preemption feature is disabled
on a node, this node continues to track all LSPs desiring
soft-preemption. This is needed in a case when
soft-preemption is re-enabled, TE will have the property
of the existing LSPs without any re-signaling.
Specifies the timeout for the soft-preempted LSP, in seconds.
The range is from 1 to 300.
commit—Saves the configuration changes and remains within
the configuration session.
end—Prompts user to take one of these actions:
• Yes— Saves configuration changes and exits the
configuration session.
• No—Exits the configuration session without committing
the configuration changes.
• Cancel—Remains in the configuration mode, without
committing the configuration changes.
