This section describes how to use the EVC model to carry L2VPN services to reduce enterprise costs.
The traditional service model supported by the NetEngine 8000 F uses either VPLS or VLL to access a carrier network. If VPLS is used, common sub-interfaces (VLAN type), dot1q VLAN tag termination sub-interfaces, or QinQ VLAN tag termination sub-interfaces must be created on the user-side interfaces of PEs and bound to different VSIs. If Layer 2 devices use different access modes on a network, network planning and management are complex and difficult. To resolve this issue and reduce enterprise costs, configure the EVC model to carry Layer 2 services.
Before configuring the EVC model to carry L2VPN services, complete the following tasks:
Configure a routing protocol on the PEs so that they can communicate at the network layer.
Configure basic Multiprotocol Label Switching (MPLS) functions, enable MPLS Label Distribution Protocol (LDP), and establish LDP Label Switched Paths (LSPs) on the PEs.
Enable MPLS L2VPN on the PEs globally.
Establish the EVC model. For details, see Establishing the EVC Model.
