What is L2VPN Juniper?

What is L2VPN Juniper?

L2VPN, also known as a pseudowire, is defined in RFC4665, where they are called Virtual Private Wire Service (VPWS): The PE devices provide a logical interconnect such that a pair of CE devices appears to be connected by a single logical Layer 2 circuit. PE devices act as Layer 2 circuit switches.

What is L2VPN used for?

A Layer 2 MPLS VPN is a term in computer networking. It is a method that Internet service providers use to segregate their network for their customers, to allow them to transmit data over an IP network. This is often sold as a service to businesses.

What is L2VPN in networking?

The L2VPN working group is responsible for defining and specifying a. limited number of solutions for supporting provider-provisioned Layer-2. Virtual Private Networks (L2VPNs). It will also address requirements. driven by cloud computing services and data centers as they apply to.

What is difference between VPLS and VPRN?

VPLS offers a balance between point-to-point pseudowire service (Epipe, Ipipe, etc.) and outsourced routed services (VPRN). Unlike VPRN service, VPLS enables each customer to maintain control of their own routing strategies.


Introduction to VPLS VPLS is an Ethernet-based point-to-multipoint Layer 2 VPN. It allows you to connect geographically dispersed Ethernet local area networks (LAN) sites to each other across an MPLS backbone.

What kind of mode does L2VPN interworking support?

L2VPN interworking does not support Ethernet VLAN (Type 4) mode. You specify the mode in the following ways: If using the older legacy CLI commands, you can use the interworking { ethernet | ip } command in pseudowire-class configuration mode.

What kind of service does L2VPN pseudowire provide?

The service provisioned with these L2VPNs is known as Virtual Private Wire Service (VPWS). PWs provide a common intermediate format to transport multiple types of network services over a Packet Switched Network (PSN) – a network that forwards packets – IPv4, IPv6, MPLS, Ethernet

Where does the L2VPN packet go on a PE router?

Frames that are received at the PE router on the AC are encapsulated and sent across the PSW to the remote PE router. The egress PE router receives the packet from the PSW and removes their encapsulation. The egress PE extracts and forwards the frame to the AC. Why is L2VPN needed?

What does EVPN MAC mean in Ethernet router?

Each EVPN MAC route announces the customer MAC address and the Ethernet segment associated with the port where the MAC was learned from and its associated MPLS label. This EVPN MPLS label is used later by remote PEs when sending traffic destined to the advertised MAC address.
