Q-in-Q 802.1ad Provider Bridge extensions also known Resulting set of interconnected devices forms a private MPLS VPN. Have a means of tunneling labeled packets amongst each other. The following discussion applies to devices that are VPLS capable and MPLS, without the need for address resolution servers or otherĮxternal servers, as discussed in. Virtual LAN services, including the appropriate flooding ofīroadcast, multicast, and unknown unicast destination traffic over It describes a simple and scalable way to offer Note that the same model can be applied to other 802.1 for transporting Ethernet/802.3 and VLAN trafficĪcross multiple sites that belong to the same L2 broadcast domain or
defines how to carry Layer 2 (L2) frames over point-to. Learning/aging on a per-pseudowire basis, and packet replicationĪcross pseudowires for multicast/broadcast traffic and for flooding To be forwarded to the proper location(s). Via an MPLS network expect broadcast, multicast, and unicast traffic Sites that belong to the same broadcast domain and that are connected Connectivity between customer Ethernet switches: LAN switchingīroadcast and multicast services are available over traditional LANs. Connectivity between customer routers: LAN routing application The intended application for the end-user canīe divided into the following two categories: Services (VPLS) is to provide connectivity between geographicallyĭispersed customer sites across MANs and WANs, as if they wereĬonnected using a LAN. The primary motivation behind Virtual Private LAN Specifically in Metropolitan and Wide Area Networks (MAN and WAN,
