ECT migration by changing ECT algorithm example
Network requirements
As shown in Figure 14, move I-SID 1000 from the original ECT algorithm to ECT algorithm 2. Change the B-VLAN for I-SID 1000 from VLAN 10 to VLAN 20.
Figure 14: Network diagram
Configuration procedure
This example uses BEB 1 to show the configuration procedure. You can configure other SPBM devices in the same way you configure BEB 1.
Configure the new B-VLAN (VLAN 20 in this example):
Perform this task on all BEBs and BCBs in the SPBM network.
# Create VLAN 20.
<BEB1> system-view [BEB1] vlan 20 [BEB1-vlan20] quit
# Map B-VLAN 20 to MSTI 4092, and activate the change.
[BEB1] stp region-configuration [BEB1-mst-region] instance 4092 vlan 20 [BEB1-mst-region] active region-configuration [BEB1-mst-region] quit
# Assign the provider network ports to VLAN 20.
[BEB1] interface ten-gigabitethernet 1/0/1 [BEB1-Ten-GigabitEthernet1/0/1] port trunk permit vlan 20 [BEB1-Ten-GigabitEthernet1/0/1] quit [BEB1] interface ten-gigabitethernet 1/0/3 [BEB1-Ten-GigabitEthernet1/0/3] port trunk permit vlan 20 [BEB1-Ten-GigabitEthernet1/0/3] quit
Map B-VLAN 20 to ECT algorithm 2.
Perform this task on all BEBs and BCBs in the SPBM network.
[BEB1] spbm [BEB1-spbm] ect 2 b-vlan 20 [BEB1-spbm] quit
Assign B-VLAN 20 to I-SID 1000.
Perform this task on all BEBs in the SPBM network.
[BEB1] vsi test [BEB1-vsi-test] spb i-sid 1000 [BEB1-vsi-test-1000] b-vlan 20 [BEB1-vsi-test-1000] quit [BEB1-vsi-test] quit [BEB1] quit
Verifying the configuration
Verify the configuration and forwarding states during ECT migration:
On BEBs (BEB 1 in this example):
# Verify the ECT migration configuration for I-SID 1000.
<BEB1> display spbm ect-migration i-sid 1000 ECT B-VLAN T R 00-80-c2-02 20 1 1 00-80-c2-03 10 1 1
The output shows that I-SID 1000 is migrating from ECT algorithm 3 to ECT algorithm 2. During this period, both B-VLAN 10 and B-VLAN 20 can transmit traffic.
# Verify that the BEB has set up unicast PWs for I-SID 1000 on both B-VLANs 10 and 20.
