Output Fields

Table 1 describes the output fields for the show spring-traffic-engineering command. Output fields are listed in the approximate order in which they appear.

Table 1: show spring-traffic-engineering Output Fields

Field Name

Field Description

To

IP address of the SR-TE LSP destination.

State

State of the SR-TE LSP:

  • Up

  • Down

LSP Name

Name of the SR-TE LSP.

S-ERO

Source Explicit Route Object (ERO), or LSP path.

Bandwidth

Bandwidth allocated for the SR-TE LSP.

Delegation info

LSP control and routing status:

  • Control-status:

    • Externally controlled—PCE has control of the source-routing path.

      This can happen when:

      • The lsp-external-controller pccd statement is configured either under the source-routing path or under the primary segment list.

      • The request path-computation-client retry-delegation lsp-name command is issued for a delegated LSP that was not previously controlled by the PCE.

    • Locally controlled—PCC has control of the source-routing path.

      This can happen when:

      • The PCE has returned the control of the source-routing path.

      • Delegation timer with the PCE has expired.

  • Routing-status: Applicable to delegated source-routing paths only.

    • Externally routed—PCE provided the ERO for the source-routing path for a delegated LSP through PCUpdate.

    • Locally routed—PCE does not provide ERO for the source-routing path.

Route preference

Route preference of the SR-TE LSP.

Number of LSPs

Statistics of the total number of SR-TE LSPs and the LSP state.

External controllers

Name of the LSP external controller. By default the only supported external controller is pccd.

BFD name

Name of the BFD session. The name is auto-generated in the V4-srte_bfd_session-id for IPv6.

The name is based on the Explicit Route Object (ERO) stack of the LSP path, that is, if multiple LSPs have same path they share the same BFD session name.

BFD status

Status of the BFD session: UP, DOWN.

Referencing LSPs

Name of referencing LSP. If the LSP does not have a path name, then the referencing LSP is displayed as unnamed path.

SR-ERO hop count

Number of hops in the segment routing ERO.

Hop 1

Represents the path of the BFD session. If any other LSP is on same path, it has the same BFD session.

Total displayed BFD sessions

Total count of all the BFD sessions.

Tunnel source

Source of the tunnel configuration; for example, static configuration.

Ingress telemetry statistics

Ingress telemetry statistics including the sensor name and ID.

Transit telemetry statistics

Transit telemetry statistics including the sensor name and ID.

ERO Valid

Indicates whether the received explicit route object (ERO) is valid or not.

Sample Output

show spring-traffic-engineering lsp name

show spring-traffic-engineering lsp detail

show spring-traffic-engineering lsp detail (BGP-SR-TE policies based tunnel)

show spring-traffic-engineering lsp detail (BGP-SR-TE policies based colored tunnels)

For colored tunnels, telemetry details is displayed.
