Parameters

lsp-id lspid: Specifies an LSP ID in SYSID.Pseudonode ID-fragment num format. The SYSID argument represents the system ID of the LSP originating node. The Pseudonode ID argument represents the ID of the pseudonode. The fragment num argument represents the LSP fragment number. If you do not specify an LSP ID, the command displays LSP information for all LSP IDs.

lsp-name lspname: Specifies the LSP name in Symbolic name-fragment num format. The Symbolic name argument represents the symbolic hostname of the LSP originating node. The fragment num argument represents the LSP fragment number. If you do not specify an LSP name, the command displays LSP information for all LSP names.

local: Displays LSPs generated by the local device. If you do not specify this keyword, the command displays information for LSPs generated by all devices.

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

Usage guidelines

If you do not specify any parameters, the command displays digests for all LSPs.

Table 16: Command output

Field

Description

LSP ID

LSP ID. An asterisk (*) indicates a local LSP.

Seq Num

LSP sequence number.

Checksum

LSP checksum.

Holdtime

LSP lifetime (in seconds).

Length

LSP length.

Overload

Overload bit in the LSP:

  • 1—Overload bit set. ISIS-SPB will not use this LSP for shortest path calculation because the LSP originating node is experiencing an LSDB error condition.

  • 0—Overload bit not set. The LSP can be used for shortest path calculation.

System ID

System ID of the LSP originating device.

NLPID

Network layer protocol running on the LSP originating device. This field is always SPBM for an SPBM node.

Area address

Area address of the LSP originating device.

MT capability TLV

Multi-topology capability TLV.

MT ID

Topology ID in a multi-topology environment.

MT overload

Overload bit in the multi-topology capability TLV:

  • 1—Overload bit set.

  • 0—Overload bit not set.

SPB instance sub-TLV

The SPB instance sub-TLV contains the SPSourceID of the LSP originating device.

CIST root identifier

This field is for SPBM that works with RSTP and MSTP at SPT Region boundaries. It is an imported value from a spanning tree.

CIST ERPC

CIST external root path cost is the cost to the CIST root. It is derived from the spanning tree algorithm.

SPSourceID

Shortest path source identifier. An SPSource ID uniquely identifies a device in an SPBM network. The SPSourceID is used for constructing multicast destination addresses for multicast frames that are originated from the LSP originating device.

Bridge priority

Bridge priority. The bridge priority and the system ID form the bridge identifier, which is a tie-breaker used in ECT algorithms for SPT computation.

Number of trees

Number of B-VLAN to ECT mappings.

U-Bit

U bit status:

  • 1—U bit set. The U bit is set if the LSP originating device can use the B-VLAN to transmit traffic.

  • 0—U bit not set. The U bit is not set if the LSP originating device cannot use the B-VLAN to transmit traffic.

ECT

ECT algorithm.

SPVID

SPBV ID. It is fixed at 0 for SPBM.

SPBM Service Identifier and Unicast Address sub-TLV

SPBM service identifier and unicast address sub-TLV.

I-SID

I-SID and the multicast group membership flags of the LSP originating device for the I-SID.

The following are the flags:

  • T—T bit set. The LSP originating device is a transmitter in the multicast group for the I-SID.

  • R—R bit set. The LSP originating device is a receiver in the multicast group for the I-SID.

This field displays (T&R) next to the I-SID if the originating device is both a receiver and a transmitter in the multicast group for the I-SID.

Extended neighbor reachability TLV

Extended neighbor reachability TLV.

Hostname

Symbolic hostname configured with the is-name command. If the LSP originating device is not assigned a hostname, this field displays its system ID.

Cost

Link metric value.

Port number

Number of ports that have adjacencies.
