4 21-4MCSIManaging ATM VLANs Copyright © 1998, Cisco Systems, Inc. Used to create a LAN backbone Defined at the MAC layer Individual emulated LANs use LANE services Participation in ELANs independent of location Each LEC is the interface to one ELAN LANE Overview

5 21-5MCSIManaging ATM VLANs Copyright © 1998, Cisco Systems, Inc. LEC acts as a LAN interface into the ATM network Each LEC is the interface to one ELAN A Catalyst® switch or Cisco router can have multiple LECs on one physical interface LEC Overview

6 21-6MCSIManaging ATM VLANs Copyright © 1998, Cisco Systems, Inc. LES Registers MAC addresses Responds to address requests BUS Distributes multicast and broadcast One LES/BUS per ELAN LES/BUS Overview

7 21-7MCSIManaging ATM VLANs Copyright © 1998, Cisco Systems, Inc. Determines which ELAN an LEC belongs to Responds to LEC requests with LES address when LEC joins an ELAN One LECS per LANE cloud LECS Overview
