BGP Routing Issues Case Study 1 - BGP configuration without filter

I learned BGP since 1998, of course, just like many other people, I made some human errors without fully understanding of BGP protocols. Just copy and paste sample configuration from cisco websites and modified it then applied to the production BGP router. However, its a dangerous thing if you just know part of something without complete knowledge and implement it on the production network.

This is the reason I want to start to share my knowledge and experience about BGP protocol. Maybe it can help some people to prevent doing some ridiculous BGP incidents over internet(ex: advertise private IP or default route to the internet)
