l Outer VLAN tag that PEs add to STP packets
l IDs of the VLANs that interfaces of PEs and CEs belong to
Procedure
Step 1 Enable STP on CEs and PEs.
# Configure CE1.
[CE1] stp enable
# Configure CE2.
[CE2] stp enable
# Configure CE3.
[CE3] stp enable
# Configure CE4.
[CE4] stp enable
Step 2 Configure CE1 and CE2 to send STP packets with VLAN tag 100 to PEs and configure CE3
and CE4 to send STP packets with VLAN tag 200 to PEs.
# Configure CE1.
[CE1] vlan 100
[CE1-vlan100] quit
[CE1] interface gigabitethernet 1/0/0
[CE1-GigabitEthernet1/0/0] port hybrid tagged vlan 100
[CE1-GigabitEthernet1/0/0] stp bpdu vlan 100
[CE1-GigabitEthernet1/0/0] quit
# Configure CE2.
[CE2] vlan 100
[CE2-vlan100] quit
[CE2] interface gigabitethernet 1/0/0
[CE2-GigabitEthernet1/0/0] port hybrid tagged vlan 100
[CE2-GigabitEthernet1/0/0] stp bpdu vlan 100
[CE2-GigabitEthernet1/0/0] quit
# Configure CE3.
[CE3] vlan 200
[CE3-vlan200] quit
[CE3] interface gigabitethernet 1/0/0
[CE3-GigabitEthernet1/0/0] port hybrid tagged vlan 200
[CE3-GigabitEthernet1/0/0] stp bpdu vlan 200
[CE3-GigabitEthernet1/0/0] quit
# Configure CE4.
[CE4] vlan 200
[CE4-vlan200] quit
[CE4] interface gigabitethernet 1/0/0
[CE4-GigabitEthernet1/0/0] port hybrid tagged vlan 200
[CE4-GigabitEthernet1/0/0] stp bpdu vlan 200
[CE4-GigabitEthernet1/0/0] quit
Step 3 Configure QinQ-based transparent transmission on PEs so that PEs add outer VLAN tag 10 to
STP packets with VLAN tag 100 and VLAN tag 200.
# Configure PE1.
