Shortest Path Bridging Configuration Terms and Definitions
| Term | Definition |
|---|---|
| Shortest Path Bridging (SPB) | Shortest Path Bridging (SPB), defined in IEEE 802.1aq, is a protocol that provides data traffic a shortest cost path between any pair of switches in the SPB network, and features dynamic route calculation in a loop-free Layer-2 network, and fast convergence time using IS-IS. |
| Base-VLAN | The VLAN located on the SPBV boundary port that manages operations in the SPT and provides access to the SPBV network. |
| Shortest Path VID (SPVID) | The VLAN located on the port internal to the SPB region used to identify a base-VLAN and SPT within the SPB network. |
| SPB Boundary Port | The SPB port packets ingress and egress the SPB region on located on the base-VLAN. |
| SPB Internal Port | A port that faces into the SPB region and is a member of the SPVID. |
| Equal Cost Tree (ECT) algorithm | One of 16 algorithms defined in the IEEE 802.1Qaq standard used to select a path among available equal cost paths. |
