Figure 20: Generic Customer Use Case For LLDP
The example displayed in Figure 20 depicts a MPLS network that uses Ethernet interfaces in the
core or as an access/handoff interfaces to connect to different kind of Ethernet enabled devices
such as service gateway/routers, QinQ switches, DSLAMs or customer equipment.
IEEE 802.1ab LLDP running on each Ethernet interfaces in between all the above network
elements may be used to discover the topology information.
