In Port mode, the configuration is performed under the l2transport configuration mode. Port Mode-In this mode, all packets reaching the port are sent over the pseudowire, regardless of any VLAN tags that are present An L2VPN Ethernet port can operate in one of two modes: Supports a point-to-point end-to-end service, where two Ethernet circuits areĬonnected together. Pseudowires, allowing users to implement different types of end-to-endīOOTP traffic (dst UDP 68) over any type of pseudowire is unsupported. The edge router sends the traffic down anotherĮnables the connection between different types of L2 attachment circuits and The traffic then tunnels through a pseudowire over the SP core Traffic from the customer travels over this link to the edge of the SPĬore network. The connection between theĬustomer site and the nearby SP edge router is known as an attachment circuit Technologies, such as Ethernet and Frame Relay. This access network may use a mixture of L2 Typically, a SP uses an access network to connect theĬustomer to the core network. Layer 2 VPNs on Gigabit Ethernet InterfacesĮnables service providers (SPs) to provide L2 services to geographicallyĭisparate customer sites. Introduces Layer 2 Virtual Private Networks (VPNs) and the corresponding Include all information related to circuits and their connections. Requires Provider Edge (PE) routers with the following capabilities:ĭata units (PDU) into Layer 3 (元) packets. While using the service provider resources to establish the network. Service, the service provider does not require information about the customer's Using the data link resources obtained from the service provider. Provider establishes Layer 2 connectivity. Requires coordination between the service provider and customer. Private Network (VPN) emulates a physical sub-network in an IP or MPLS network,īy creating private connections between two points.
