3) Configuration on third-party devices
Configure the third-party devices between Provider A and Provider B as follows: configure the port
connecting GigabitEthernet 1/0/3 of Provider A and that connecting GigabitEthernet 1/0/3 of Provider B
to allow tagged frames of VLAN 10 and 50 to pass through.

Network requirements
As shown in Figure 10-5 ,
z
Provider A and Provider B are edge devices on the service provider network and are
interconnected through trunk ports. They belong to SVLAN 1000 and SVLAN 2000 separately.
z
Customer A, Customer B and Customer C are edge devices on the customer network.
z
Third-party devices with a TPID value of 0x8200 are deployed between Provider A and Provider
B.
Make configuration to achieve the following:
z
VLAN 10 frames of Customer A and Customer B can be forwarded to each other across SVLAN
1000;
z
VLAN 20 frames of Customer A and Customer C can be forwarded to each other across SVLAN
2000.
