Procedure
Step 1 Configure basic SEP functions.
1. Configure a SEP segment with the ID being 1 and a control VLAN with the ID being 10.
# Configure PE1.
<Quidway> system-view
[Quidway] sysname PE1
[PE1] sep segment 1
[PE1-sep-segment1] control-vlan 10
[PE1-sep-segment1] protected-instance all
[PE1-sep-segment1] quit
# Configure PE2.
<Quidway> system-view
[Quidway] sysname PE2
[PE2] sep segment 1
[PE2-sep-segment1] control-vlan 10
[PE2-sep-segment1] protected-instance all
[PE2-sep-segment1] quit
# Configure LSW1.
<Quidway> system-view
[Quidway] sysname LSW1
[LSW1] sep segment 1
[LSW1-sep-segment1] control-vlan 10
[LSW1-sep-segment1] protected-instance all
[LSW1-sep-segment1] quit
# Configure LSW2.
<Quidway> system-view
[Quidway] sysname LSW2
[LSW2] sep segment 1
[LSW2-sep-segment1] control-vlan 10
[LSW2-sep-segment1] protected-instance all
[LSW2-sep-segment1] quit
# Configure LSW3.
<Quidway> system-view
[Quidway] sysname LSW3
[LSW3] sep segment 1
[LSW3-sep-segment1] control-vlan 10
[LSW3-sep-segment1] protected-instance all
[LSW3-sep-segment1] quit
2. Add PE1, PE2 and LSW1 to LSW3 to Segment1 and configure roles of interfaces.
NOTE
By default, STP is enabled on a interface. Before adding an interface to a SEP segment, disable STP
on the interface.
# Configure PE1.
[PE1] interface gigabitethernet 1/0/1
[PE1-GigabitEthernet1/0/1] stp disable
[PE1-GigabitEthernet1/0/1] sep segment 1 edge primary
[PE1-GigabitEthernet1/0/1] quit
# Configure LSW1.
[LSW1] interface gigabitethernet 1/0/1
[LSW1-GigabitEthernet1/0/1] sep segment 1 edge no-neighbor primary
[LSW1-GigabitEthernet1/0/1] quit
[LSW1] interface gigabitethernet 1/0/2
[LSW1-GigabitEthernet1/0/2] stp disable
[LSW1-GigabitEthernet1/0/2] sep segment 1
[LSW1-GigabitEthernet1/0/2] quit
# Configure LSW2.
[LSW2] interface gigabitethernet 1/0/1
