2. Configure the Layer 2 forwarding function on CE1 and Router1 to Router5.
Procedure
Step 1 Configure basic SEP functions.
1. Configure SEP segment 1 on Router1 to Router5 and configure VLAN 10 as the control
VLAN of SEP segment 1.
# Configure Router1.
<Huawei> system-view
[Huawei] sysname Router1
[Router1] sep segment 1
[Router1-sep-segment1] control-vlan 10
[Router1-sep-segment1] protected-instance all
[Router1-sep-segment1] quit
# Configure Router2.
<Huawei> system-view
[Huawei] sysname Router2
[Router2] sep segment 1
[Router2-sep-segment1] control-vlan 10
[Router2-sep-segment1] protected-instance all
[Router2-sep-segment1] quit
# Configure Router3.
<Huawei> system-view
[Huawei] sysname Router3
[Router3] sep segment 1
[Router3-sep-segment1] control-vlan 10
[Router3-sep-segment1] protected-instance all
[Router3-sep-segment1] quit
# Configure Router4.
<Huawei> system-view
[Huawei] sysname Router4
[Router4] sep segment 1
[Router4-sep-segment1] control-vlan 10
[Router4-sep-segment1] protected-instance all
[Router4-sep-segment1] quit
# Configure Router5.
<Huawei> system-view
[Huawei] sysname Router5
[Router5] sep segment 1
[Router5-sep-segment1] control-vlan 10
[Router5-sep-segment1] protected-instance all
[Router5-sep-segment1] quit
NOTE
l The control VLAN must be a VLAN that has not been created or used, but the configuration file
automatically displays the command for creating the VLAN.
l Each SEP segment must be configured with a control VLAN. After an interface is added to the
SEP segment configured with a control VLAN, the interface is automatically added to the control
VLAN.
2. Add all devices on the ring to SEP segment 1 and configure interface roles on the devices.
