   IEEE 802.1ad implements standard protocols for double tagging of data. The data traffic coming from the customer side are double tagged in the provider network where the inner tag is the customer-tag (C-tag) and the outer tag is the provider-tag (S-tag).

   Configuring IEEE 802.1ad. Provider networks handle trafic from a large number of customers. It is important that one customer’s trafic is isolated from the other customer’s trafic. IEEE 802.1ad enables the service providers to use the architecture and protocols of IEEE 802.1Q to offer separate LANs, bridged local area networks, or virtual ...

   How does IEEE 802.1ad work?

   • By using a different set of addresses for the Layer 2 protocols running in provider bridges, IEEE 802.1ad causes customers' Layer 2 PDUs entering the provider bridge to appear as unknown multicast traffic and forwards it on customer ports (on the same S-VLAN). Customers' Layer 2 protocols can then run transparently.

   What is a s-Bridge in IEEE 802.1ad?

   • The S-bridge component is capable of inserting or removing a service provider VLAN (S-VLAN) for all traffic on a particular port. IEEE 802.1ad adds a new tag called a Service tag (S-tag) to all ingress frames from the customer to the service provider. The VLAN in the S-tag is used for forwarding the traffic in the service provider network.

   No changes are required to convert 802.1Q to 802.1ad beyond assigning a new Provider Bridge Address block and a Provider Tag Ethertype. This is sufficient provided that: All customer traffic maps to a single provider service instance. All customer traffic has the same priority in the provider network.

   802.1ad - Provider Bridges. This amendment to IEEE Std 802.1Q-1998 is intended to develop an architecture and bridge protocols, compatible and interoperable with existing Bridged Local Area Network protocols and equipment, to provide separate instances of the MAC services to multiple independent users of a Bridged Local Area Network in a manner ...
