display mpls te tunnel path

Function

The display mpls te tunnel path command displays the path of an MPLS TE tunnel.

Format

display mpls te tunnel path [ [ [ tunnel-name ] tunnel-name ] [ lsp-id ingress-lsr-id session-id lsp-id ] | fast-reroute { local-protection-available | local-protection-inuse } | lsr-role { ingress | transit | egress } ]

display mpls te tunnel path expanded tunnel-name tunnel-name [ lsp-id ingress-lsr-id session-id lsp-id ]

display mpls te tunnel path expanded lsp-id ingress-lsr-id session-id lsp-id

Parameters

Parameter	Description	Value
tunnel-name tunnel-name	Specifies the name of an MPLS TE tunnel. If the mpls te signalled tunnel-name command has been used to configure a tunnel name, this specified name is used.	The value is an existing tunnel name.
ingress-lsr-id	Specifies the LSR ID of the ingress.	The value is in dotted decimal notation.
session-id	Specifies the ID of a session.	The value is an integer that ranges from 0 to 65535.
lsp-id	Specifies the LSP ID.	The value is an integer that ranges from 0 to 65535.
fast-reroute local-protection-available	Specifies the available path for local protection of FRR.	-
fast-reroute local-protection-inuse	Specifies the path in use for local protection of FRR.	-
lsr-role { ingress \| transit \| egress }	Indicates the role of an LSR. ingress: indicates the ingress LSR. transit: indicates the transit LSR. egress: indicates the egress LSR.	-
expanded	Displays the expanded LSP path information by completing the RRO information.	-

Usage Guidelines

Usage Scenario

The display mpls te tunnel path command displays information about the path of an MPLS TE tunnel.

If no tunnel name is specified, information about all MPLS TE tunnels' path attributes is displayed.

When a Huawei device is interconnected with a non-Huawei device and the RRO information carried in the packet sent by the non-Huawei device is incomplete, the RRO information can be complemented using the display mpls te tunnel path expanded command on the Huawei device to display the information about the entire LSP path.

Precautions

The system can record and display the paths only after the mpls te record-route command is configured.
