Parameters

egress: Displays the LSPs taking the current LSR as egress.

in-label label-value: Displays the LSPs using the specified label as the incoming label, in the range of 0 to 1048575.

ingress: Displays the LSPs taking the current LSR as ingress.

outgoing-interface interface-type interface-number: Displays the LSPs using the specified interface as the outgoing interface. The interface-type interface-number argument specifies an interface by its type and number.

protocol: Displays the LSPs established by a protocol.

bgp: Displays BGP LSPs.

ldp: Displays LDP LSPs.

local: Displays the LSPs to the direct next hops, or the LSPs that use the local MPLS TE tunnel interfaces as the LSP heads.

rsvp-te: Displays CRLSPs established by RSVP-TE.

static: Displays static LSPs.

static-cr: Displays static CRLSPs and static SRLSPs.

transit: Displays the LSPs taking the current LSR as a transit LSR.

vpn-instance vpn-instance-name: Displays LSPs for the specified MPLS L3VPN instance. The vpn-instance-name is a case-sensitive string of 1 to 31 characters. If you do not specify this option, the command displays LSPs for the public network.

ipv4-address mask-length: Displays the IPv4 LSP for an FEC specified by an IPv4 address and a mask length. The value range for the mask length is 0 to 32.

verbose: Displays detailed LSP information. If you do not specify this keyword, the command displays brief LSP information.

Usage guidelines

If you do not specify any parameters, this command displays brief information about all LSPs. If you specify only the verbose keyword, this command displays detailed information about all LSPs.

Table 4: Command output

Field

Description

FEC

Forwarding equivalence class:

  • IP address/mask—Classifies FECs by destination address.

  • IP address—Classifies FECs by next hop.

  • IP address/Out Label—Classifies FECs by next hop and outgoing label.

  • Ingress LSR ID/Tunnel ID/LSP ID—RSVP TE FEC.

  • - (a hyphen)—The LSP is a static transit LSP, static egress LSP, adjacency path for static SRLSPs, static transit CRLSP, or static egress CRLSP.

  • Backup—The LSP is a backup LSP of the previous LSP.

Proto

Label distribution protocol:

  • LDP.

  • BGP.

  • RSVP.

  • Static.

  • StaticCR—Static CRLSP or static SRLSP.

  • Local—LSP to a direct next hop, or LSP that uses a local MPLS TE tunnel interface as the LSP head.

In/Out Label

Incoming label/outgoing label.

Interface/Out NHLFE

Outgoing interface name or NHLFE entry index.

NHLFEnumber specifies the outer LSP that carries the current LSP. The outer LSP is that matches the NHLFE entry with an NID of number.
