Configuration example
Network requirements
As shown in Figure 20, Site 1 and Site 2 in VPN A are two branches of a company, and they use
VLAN 5 to transmit traffic. Because Site 1 and Site 2 are located in different areas, the two sites use
the VPN access service of a service provider. The service provider assigns VLAN 100 to the two
sites.
Configure nesting, so that the two branches can communicate through the service provider network.
