   What is s-Bridge in IEEE 802.1ad?

   • Figure 1 shows the topology. 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.

   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.

   How many MAC addresses does a provider Bridge use?

   • The IEEE has reserved 33 Layer 2 MAC addresses for customer devices operating Layer 2 protocols. If a provider bridge uses these standard MAC addresses for its Layer 2 protocols, the customers' and service provider's Layer 2 traffic will be mixed together.

   Service provider bridges (also called provider bridges) allow devices in a service provider network to transparently carry the Layer 2 control frames of a customer. Spanning Tree Protocol (STP) bridge protocol data units (BPDUs) or Cisco Discovery Protocol frames are carried separately from the service provider traffic and from other customer ...
