Organize the LLDPDU exchange and proceeding between ESR-1 and ESR-2 routers or between two controllers.
Solution:
R1 configuration
Enable LLDP globally on the router:Блок кода esr(config)# lldp enable
Enable the receiving and transmission of LLDPDU on the gi 1/0/1 interface.
Блок кода esr(config)# interface gigabitethernet 1/0/1 esr(config-if-gi)# lldp receive esr(config-if-gi)# lldp transmit
R2 configuration
Enable LLDP globally on the router/controller:
Блок кода esr(config)# lldp enable
Enable the receiving and transmission of LLDPDU on the gi 1/0/1 interface.
Блок кода esr(config)# interface gigabitethernet 1/0/1 esr(config-if-gi)# lldp receive esr(config-if-gi)# lldp transmit
To view LLDP neighbors information, use the following command:
Блок кода esr# show lldp neighbors
To view more detailed information on the certain interface neighbor, use the following command:
Блок кода esr# show lldp neighbors gigabitethernet 1/0/1
To view LLDP statistics, use the following command:
Блок кода esr# show lldp statistics
...
To establish a PPP connection through the E1 stream, there must be TOPGATE-WAN-E1 media converter in the ESR router or WLC controller.
