Thanks, think I got it. Also the diagram in this page (firewall.cx/cisco-technical-knowledgebase/cisco-routers/…) helped me to understand better what you are saying.

Pardon my foolish question, why use the virtual end points, 1.1.1.1 and 2.2.2.2, why not use 172.16.1.1 and 172.16.1.2? Why the former two are special?

comment IP addressing/subnetting
If you are really interested in subnetting, you need to do some serious study. Some ready made solution from others will never allow you to cope with changes or future growths. Since you are an IT administrator, I presume that you have enough backgrounds to quickly grasp the topics. Look for subnetting over Internet, and study the materials. But remember, understanding subnetting needs real devotion and willingness to learn. For some people, it can be mind baffling.

@ShaneMadden Perhaps not, all three routers are exactly identical, running the same IOS.

comment Routers do not Synchronize Clock using NTP
Found the bug, the actual command at the routers should have been ntp server 192.168.10.2 key 1. I did not assign key value, and the routers were using the default 0. But why did R1 synchronize?
