Transportation of Service Using Ethernet over MPLS
Ethernet over MPLS (EoMPLS) PWs provide a tunneling mechanism for Ethernet traffic through an
MPLS-enabled Layer 3 core network. EoMPLS PWs encapsulate Ethernet protocol data units (PDUs)
inside MPLS packets and use label switching to forward them across an MPLS network. EoMPLS PWs
are an evolutionary technology that allows you to migrate packet networks from legacy networks while
providing transport for legacy applications. EoMPLS PWs also simplify provisioning, since the provider
edge equipment only requires Layer 2 connectivity to the connected customer edge (CE) equipment. The
Cisco ME 3600X 24CX Series Switch implementation of EoMPLS PWs is compliant with the RFC 4447
and 4448 standards.
The Cisco ME3600-24CX Switch supports VLAN rewriting on EoMPLS PWs. If the two networks use
different VLAN IDs, the router rewrites PW packets using the appropriate VLAN number for the local
network.
