Figure 1: LLDP Internal Architecture for a Network Node
In order to detect and address network problems and inconsistencies in the configuration, the
network operators can discover the topology information using LLDP. The Standard-based tools
address the complex network scenarios where multiple devices from different vendors are
interconnected using Ethernet interfaces.
The example displayed in Figure 2 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.
The topology information of the network in Figure 2 can be discovered if, IEEE 802.1ab LLDP is
running on each of the Ethernet interfaces in network.
