# Configure Router4.
[Router4] sep segment 2
[Router4-sep-segment2] control-vlan 10
[Router4-sep-segment2] quit
NOTE
l The control VLAN must be a new one.
l The command used to create a common VLAN is automatically displayed in a configuration file.
l Each SEP segment must be configured with a control VLAN. After being added to a SEP segment
configured with a control VLAN, an interface is added to the control VLAN automatically. You do
not need to run the port trunk allow-pass vlan command. In the configuration file, the port trunk
allow-pass vlan command, however, is displayed in the view of the interface added to the SEP segment.
Step 2 Configure SEP protected instances, and configure mappings between SEP protected instances
and user VLANs.
# Configure Router1.
[Router1] vlan batch 100 to 500
[Router1] sep segment 1
[Router1-sep-segment1] protected-instance 1
[Router1-sep-segment1] quit
[Router1] sep segment 2
[Router1-sep-segment2] protected-instance 2
[Router1-sep-segment2] quit
[Router1] stp region-configuration
[Router1-mst-region] instance 1 vlan 100 to 300
[Router1-mst-region] instance 2 vlan 301 to 500
[Router1-mst-region] active region-configuration
[Router1-mst-region] quit
The configurations of Router2 to Router4 are similar to that of Router1, and are not mentioned
here. For details, see the configuration files.
Step 3 Add all the devices on the ring network to the SEP segments and configure interface roles.
NOTE
By default, STP is enabled on a Layer 2 interface. Before adding an interface to a SEP segment, disable
STP on the interface.
# On Router1, configure GE7/0/1 as the primary edge interface and GE7/0/3 as the secondary
edge interface.
[Router1] interface gigabitethernet 7/0/1
[Router1-GigabitEthernet7/0/1] stp disable
[Router1-GigabitEthernet7/0/1] sep segment 1 edge primary
[Router1-GigabitEthernet7/0/1] sep segment 2 edge primary
[Router1-GigabitEthernet7/0/1] quit
[Router1] interface gigabitethernet 7/0/3
[Router1-GigabitEthernet7/0/3] stp disable
[Router1-GigabitEthernet7/0/3] sep segment 1 edge secondary
[Router1-GigabitEthernet7/0/3] sep segment 2 edge secondary
[Router1-GigabitEthernet7/0/3] quit
# Configure Router2.
[Router2] interface gigabitethernet 7/0/1
[Router2-GigabitEthernet7/0/1] stp disable
[Router2-GigabitEthernet7/0/1] sep segment 1
[Router2-GigabitEthernet7/0/1] sep segment 2
[Router2-GigabitEthernet7/0/1] quit
[Router2] interface gigabitethernet 7/0/2
[Router2-GigabitEthernet7/0/2] stp disable
[Router2-GigabitEthernet7/0/2] sep segment 1
[Router2-GigabitEthernet7/0/2] sep segment 2
