MAC addresses and relearn MAC addresses after the topology of the lower-layer network
changes. This ensures nonstop traffic forwarding.

Configuration Roadmap
The configuration roadmap is as follows:
1. Configure basic SEP functions.
(1) Configure SEP segment 1 on LSW1 to LSW3 and configure VLAN 10 as the control
VLAN of SEP segment 1.
(2) Add LSW1 to LSW3 to SEP segment 1 and configure port roles on the edge devices
of the SEP segment, namely, LSW1 and LSW2.
NOTE
PE1 and PE2 do not support the SEP protocol; therefore, the ports of LSW1 and LSW2
connected to the PEs must be no-neighbor edge ports.
(3) On the device where the no-neighbor primary edge port is located, specify the port in
the middle of the SEP segment as the port to block.
(4) Configure manual preemption.
