4.2 Example: Configuring VLAN Stacking Multi-ISP
Wholesale Access
In a Layer-2 switching metropolitan area network (MAN), there are multiple Internet service
providers (ISPs). To provision the services provided by the ISP to the specified user group
rapidly, the outer VLAN tags of VLAN stacking can be used to identify ISPs, while the inner
VLAN tags to identify users. In this way, different user groups can be connected to the specified
ISPs in batches through different outer VLAN tags to obtain services from the ISPs.

access.
Enterprise 1 and 2 belong to ISP 1, and enterprise 3 and 4 belong to ISP 2. Based on the VLAN
stacking feature. The upper-layer network must work in the Layer 2 mode, and must forward
packets according to the VLAN and the MAC address. The MA5600T/MA5603T/MA5608T
adds the outer VLAN tag to differentiate ISPs and inner VLAN tag to differentiate users and
forwards the user packet to the Layer 2 network. Then the Layer 2/Layer 3 LAN switch forwards
the user packets to the specified ISP BRAS based on the outer VLAN tag. The ISP BRAS

Network devices and lines must be in the normal state.
The authentication data of the access user must be configured on the BRAS.
The system is working properly.
The two ISPs in the Layer-2 switching MAN provide broadband services to enterprise users.
Different enterprise user groups are bulk connected to the specified ISP to obtain services
provided by the ISP.
The access device uses xDSL or LAN access.
