RE: show run "no auto-summary" command

The same is true for synchronization in BGP:

R2#show ip protocols | section bgp
Routing Protocol is "bgp 248"
  Outgoing update filter list for all interfaces is not set
  Incoming update filter list for all interfaces is not set
  IGP synchronization is disabled
  Automatic route summarization is disabled
  Neighbor(s):
    Address FiltIn FiltOut DistIn DistOut Weight RouteMap
    46.0.0.8
    169.254.129.19
  Maximum path: 1
  Routing Information Sources:
    Gateway Distance Last Update
    46.0.0.8 200 00:08:34
  Distance: external 20 internal 200 local 200

Don't try to memorize default options in the code, it's a waste of time since it changes between releases. Instead learn how to verify the state of the network from commands other than "show run". This will also help you extend your knowledge between platforms, e.g. from IOS to IOS XR, NX-OS, ASA, etc. If you want to know the default option of a command just check the command reference for that particular version and it'll tell you what the default is.

ALL -
OK, I get that and understand that it's behavior change in 15 code and "auto-summary" and "synchronization" is not showing in the running config.
But, nobody in this forum has provided a solution or said how I can check if the "auto-summary" and "synchronization" is working as expected.
