7.2.3 Creating EPLn Service

Purpose

The Ethernet LAN service is added with MPLS or Stack VLAN protocol for processing on the basis of the original Layer 2 switching service, achieving fast forwarding and VCTRUNK bandwidth sharing. Logically the whole Ethernet LAN domain can be regarded as a huge switch. A user can access the switch from any ports in the domain. The port of this switch supports Layer 2 protocols, such as spanning tree and Internet group management protocol (IGMP Snooping).

The Ethernet private LAN (EPLn) is a simple application of the Ethernet LAN service. In this case, the VCTRUNK port cannot be shared.
