Description
LSP ID. An asterisk (*) indicates a local LSP.
LSP sequence number.
LSP checksum.
LSP lifetime (in seconds), which decreases as time elapses.
LSP length.
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 of the LSP originating device.
Network layer protocol running on the LSP originating device. This field is always
SPBM for an SPBM node.
Area address of the LSP originating device.
Multi-topology capability TLV.
Topology ID in a multi-topology environment.
Overload bit in the multi-topology capability TLV:
•
1—Overload bit set.
•
0—Overload bit not set.
The SPB instance sub-TLV contains the SPSourceID of the LSP originating device.
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 external root path cost is the cost to the CIST root. It is derived from the
spanning tree algorithm.
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. 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 B-VLAN to ECT mappings.
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 algorithm.
SPBV ID. It is fixed at 0 for SPBM.
