Use the ashowip eigrpneigborv command on router R1 to view R1s EIGRP neighbors, which displays the following.R2#show ip eigrp neighbors IP-EIGRP neighbors for process 100H Address 1 12.1.1.1 0 21.1.1.1 Interface Sel/0 Fa0/0 Hold Uptime SRTT (sec) 80 00:01:34 12 03:36:29 (ms) 8 16 RTO Q Cnt 200 0 200 0 Seq Num 76 17As you can see from the output above, R2 and R1 have established a neighbor relationship twice using the serial and Fast Ethernet interfaces, respectively. the serial interface shows a can hold time of 80 seconds, which under normal circumstances would be no less than 60 seconds; the Fast Ethernet interface shows a hold time of 12 seconds, which under normal circumstances would be no less than 10 seconds.Q Note: In EIGRP, neighboring routers are not required to have the same Hello interval and hold time. In the OSPF protocol, which will be discussed later, the neighboring routers must have the same Hello interval and hold time, or the neighbor relationship fails.2. ACK (Acknowledgement) PacketEIGRP routers use an acknowledgement packet to indicate the receipt of an EIGRP packet during an interaction, which feels a bit like TCP's acknowledgement retransmission. The EIGRP receiving router must acknowledge the sender's message to ensure that reliable communication is provided between routers. Unlike the multicast Hello packet, the acknowledgement packet is unicast and is sent only to a specific router. For efficiency, acknowledgement packets can also be piggybacked on other types of EIGRP packets, such as reply packets. 3.Update (update) packets are used when a router discovers a new neighbor. An EIGRP router sends a unicast update packet to a new neighbor so that it can be added to the topology table. Update packets are also used when a router detects a topology change. In this case, the EIGRP router sends multicast update groups to all neighborsgroups to alert them of this change. The update group, whether unicast or multicast, needs to be acknowledged as being reliably transmitted. 4.
