Mapping B-VLANs to an ECT algorithm

An ECT algorithm represents a set of tie-breakers for calculating SPTs.

To improve link efficiency in an SPBM network, you can distribute B-VLAN traffic along different paths by mapping B-VLANs to different ECT algorithms.

To ensure correct SPT calculation for a B-VLAN, the B-VLAN to ECT algorithm mappings must be the same across the SPBM network.

For more information about the ECT algorithms, see IEEE 802.1aq SPB.
