MPLS - Layer 2 VPNs

MPLS - Virtual Private Network (VPN)

Networks - Spanning Layer 2 networks across remote sites

Virtual Private LAN Service (VPLS)

Virtual Private Wire Service (VPWS)


Pseudowire is a feature that allows you to create a Layer 2 connection between two remote devices, over a Layer 3 infrastructure. An example of where pseudowire is applied is in the [L2TPv3](/l2tpv3) protocol.

Within the context of [MPLS](/mpls), pseudowire is used to provide end-to-end services across an MPLS network.

Pseudowire in MPLS can be used to deliver two types of services:

- [Virtual Private LAN Service (VPLS)](/virtual-private-lan-service-vpls)
- [Virtual Private Wire Service (VPWS)](/virtual-private-wire-service-vpws)
