Next, analyze the 3 EIGRP routes.The first one, "D2.0.0.0/8 is a summary, 00:34:22, NuHO", is a summary route on R2, and EIGRP uses "auto-summary" by default, which is used when R2 puts 2.2.0.0/24 and When R2 announces 2.2.1.0/24 from R2's S1/0 interface, the IP address of the SU0 interface is 12 1.2/24,here is already the boundary of the 2.0.0.0/8 network, R2 automatically summarizes the two explicit routes and summarizes them into the main class network 2.0.0.0/8o EIGRP and RIP are different, EIGRP automatically generates a summary route locally pointing to the Null 0 interface, and as to why a summary route is generated pointing to the Null 0 interface, as explained earlier, it is mainly used to avoid routing loops.The second UD12.0.0.0/8isasummary,00:00:03,Null.", is another summary route on R2 when R2 announces I2.LI.0/24 and 12.1.2.0/24 out of R2's LoO and Lol interfaces, the IP addresses of the LoO and Lol interfaces belong to 2.0.0.0/8, which is already the boundary of the 12.0.0.0/8 network, R2 automatically summarizes the two explicit routes and summarizes them into the main class network 12.000/8. Some readers wonder why they are not automatically summarized on R1. The reason is that both interfaces on R1 are in the primary class network, 12.0.0.0/8, and there are no primary class network boundaries that would automatically generate a summary.In particular, it is worth mentioning that you cannot set the physical interface as a passive interface in EIGRP, but you can set the loopback interface as a passive interface to reduce the resource usage. Use the following command to set the two loopback interfaces of R2 as passive interfaces: R2(config)#router eigrp 100227':CCNA Study and Lab Guide
