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:
|
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:
|
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:
|
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:
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. |
