ECT migration by changing B-VLAN example
Network requirements
As shown in Figure 13, deploy an SPBM network to meet the following requirements:
Use I-SID 3001 to extend VLAN 100 across customer sites 1, 2, and 3.
Move I-SID 3001 from the original ECT algorithm to ECT algorithm 9. Change the B-VLAN from 3001 to 3003 for I-SID 3001.

Configuration procedure
Configure BEB 1:
# Create VLAN 100, B-VLAN 3001, and B-VLAN 3003.

Repeat the previous steps to configure the MST parameters and SPBM feature on BEB 2. (Details not shown.)
Configure BCB 1:
# Create B-VLAN 3001 and B-VLAN 3003.
<BCB1> system-view [BCB1] vlan 3001 [BCB1-vlan3001] quit [BCB1] vlan 3003 [BCB1-vlan3003] quit

Configure BCB 2 in the same way you configure BCB 1. (Details not shown.)
Perform ECT migration:
# On BEB 1, change the B-VLAN to 3003 for the SPB VSI test.
[BEB1] vsi test [BEB1-vsi-test] spb i-sid 3001 [BEB1-vsi-test-3001] b-vlan 3003 [BEB1-vsi-test-3001] quit [BEB1-vsi-test] quit
# Configure BEB 2 in the same way you configure BEB 1. (Details not shown.)
Verifying the configuration
Before you perform ECT migration, verify the configuration on BEBs (for example, BEB 1):
# Verify that the BEB has ISIS-SPB adjacencies with all its neighbors.
