Usage Guidelines

**Table 1** Description of the display mpls te hot-standby state command output
Item	Description
session id	Session ID, which is the configured tunnel ID.
main LSP token	Index of the primary CR-LSP.
hot-standby LSP token	Index of the hot-standby CR-LSP.
HSB switch result	Result of a switchover: Primary LSP: indicates that data is switched to the primary CR-LSP. Hot-standby LSP: indicates that data is switched to the hot-standby CR-LSP. Ordinary LSP: indicates that data is switched to the ordinary CR-LSP. Best-Effort LSP: indicates that data is switched to the best-effort path.
HSB switch reason	Reason why traffic is switched to the hot-standby LSP.
WTR config time	WTR time. If a primary CR-LSP recovers from a fault, the system waits for a period of time, or the WTR time, to switch data from the hot-standby CR-LSP or best-effort path to the primary LSP.
WTR remain time	WTR remain time.
using overlapped path	Whether the path of the primary tunnel and the path of the backup tunnel overlap: yes: indicates that they overlap. no: indicates that they do not overlap. -: indicates that the system does not check whether they overlap.
