Table 93 show mpls forwarding-table Field Descriptions
Field Description
Local label Label assigned by this router.
• [H]—Local labels are in holddown, which means that the application that
requested the labels no longer needs them and stops advertising them to its
labeling peers.
The label’s forwarding-table entry is deleted after a short, application-
specific time.
If any application starts advertising a held-down label to its labeling peers
,
the label could come out of holddown.
Note[H] is not shown if labels are held down globally.
A label enters global holddown after a stateful switchover or a restart
of certain processes in a Cisco IOS modularity environment.
• [T]—The label is forwarded through an LSP tunnel.
NoteAlthough [T] is still a property of the outgoing interface, it is shown in
the Local label column.
• [HT]—Both conditions apply.
