EoMPLS – Pseudowire Tunnel (Ethernet Port Mode)
EoMPLS – Pseudowire Tunnel (Ethernet Port Mode)
Ethernet over MPLS (EoMPLS) with Pseudowire Tunnel in Ethernet Port Mode is a technology that extends Ethernet services over a Multiprotocol Label Switching (MPLS) network. In this configuration, a pseudowire tunnel is established to create a virtual point-to-point connection between two Ethernet ports. This allows the transparent transmission of Ethernet frames across an MPLS infrastructure, enabling the connection of geographically dispersed Ethernet-based networks as if they were part of the same local network. EoMPLS in Ethernet Port Mode is particularly valuable for service providers and enterprises seeking to interconnect remote sites or data centers seamlessly, providing a scalable and efficient solution for extending Ethernet connectivity over MPLS networks. The pseudowire tunnel encapsulates Ethernet frames within MPLS packets, ensuring reliable and secure transport across the MPLS infrastructure.

**NOTE:** As seen above VC labels are exchanged between PE routers after the targeted-LDP session is established. It
also shows each peer sends a Label Mapping message which contains FEC TLV, Label TLV and optional interface
parameters. VC Type 5 indicates Ethernet Port mode.
