3.5.1 Example for Configuring LLDP on the Device That Has a
Single Neighbor
After LLDP is configured on the network devices, the NMS can obtain the network topology.
The following example describes how to configure LLDP on the devices that have a single
neighbor.
Networking Requirements
, RouterA is directly connected to RouterB and media endpoint (ME).
The NMS needs to obtain Layer 2 information about RouterA, RouterB, and ME. By using the
Layer 2 information, a network administrator can learn about the detailed network topology
information and configuration conflicts. These requirements can be met by configuring LLDP
on RouterA and RouterB.
In addition, the administrator requires that RouterA and RouterB send LLDP traps to the NMS
when the LLDP management address changes, global LLDP is enabled or disabled, or the
neighbor information changes. This ensures that the administrator detects topology changes in
time.
The ME supports the LLDP function. Reachable routes exist between the NMS and Routers.
The SNMP parameters are set on all devices.

Configuration Roadmap
The configuration roadmap is as follows:
1.
Enable global LLDP on RouterA and RouterB.
2.
Configure management addresses for RouterA and RouterB.
3.
Enable the LLDP trap function on RouterA and RouterB.
