1. Basic configuration such as IP address configuration
2. Configure EIGRP protocol
R1 (config) #router eigrp 1 Enable EIGRP routing protocol process, AS number is 1
R1 (config-router) #network 172.16.1.0 0.0.0.255 announce network segment, subnet + anti-mask form
R1 (config-router) #network 192.168.1.4 0.0.0.3
R1 (config-router) #network 12.1.1.0 0.0.0.255
R1 (config-router) #no auto-summary need to turn off the automatic summary
R2 (config) #router eigrp 1
R2 (config-router) #network 192.168.1.4 0.0.0.3
R1 (config-router) #network 12.1.1.0 0.0.0.255
R2 (config-router) #network 10.10.10.0 0.0.0.255
R2 (config-router) # no auto-summary need to turn off automatic summarization
3. View router information
R1 # show ip protocols View routing protocol
R1 # show ip eigrp neighbors View neighbor list
R1 # show ip eigrp topology View topology database
R1 # show ip eigrp interfaces View interface status running EIGRP protocol
R1 # show ip eigrp traffic Report the statistics of EIGRP sent and received data packets.
R1 # debug eigrp packets Display the sent and received EIGRP data packets.
R1 # debug eigrp neighbors View the establishment of neighbor relationships (PT simulator does not have this command)
R1 # debug ip eigrp Monitor IP EIGRP routing event information (PT simulator does not have this command)
