Lab Topology:
Please use the following topology to complete this lab exercise:
Task 1:
Configure the hostnames on R1 and R3 as illustrated in the topology.
Task 2:
Configure the IP addresses on the Ethernet interfaces of R1 and R3 as illustrated in the topology. There is no need to configure the Loopback interfaces for this lab.
Task 3:
Disable CDP globally on both routers and enable LLDP (it’s disabled by default).
Task 4:
Make sure that both R1 and R3 have found each other via their Ethernet links using LLDP.
Task5:
Now disable one of the interfaces to prevent it from sending LLDP traffic.
