Ethernet over MPLS

EoMPLS, as specified in the draft-martini allows Layer 2 Ethernet frames to be transported across a Multiprotocol Label Switching (MPLS) core network. For the label switch router (LSR) to switch Layer 2 virtual circuits (VC), it must have IP connectivity to transport any Layer 2 attachment services. Thus, the edge LSRs must have the capability to switch Layer 2 VCs.

The EoMPLS can configured as below.
  •  Router to RouterPort Based
  •  Router to RouterVLAN Based
  •  VLAN Rewrite
  •  Switch to SwitchVLAN Based
  •  Switch to SwitchPort Based
  • VLAN Rewrite in Cisco 12000 Series Routers

 The Below link show how to configure Router to Router VLAN Based EoMPLS.
