Guy, In JUNOS BGP, everything is in a group, in IOS it is called peer-group, the purpose is to group neighbors sharing similar configurations, if IOS has some problems when providing this convenience, I think I would want to call it a bug.
I am not following the explanation from the web page, can anybody tell me what problem it will cause based on reading this article?
