Home Routing BGP BGP troubleshooting - Global routing review by iBGPlay

BGP(Border Gateway Protocol) is a global routing protocol which is commonly used between BGPlay logodomains, well-known example is Internet. BGP troubleshooting is one of hassel for network administrator. Not only difficulty level, but also hard to collect information of output. Especially BGP with ISP links. You can open a ticket and ask some information, but they won't give you details due to confidential information(?). You can use public routeservers or looking glass, but it doesn't give you what has been changed on Internet. If your BGP link to ISP is fine, but you got below complaints from users

  • Throughput is getting slow.
  • VPN link drops
  • Slow browsing experience
  • Application performance drops

What was going on??? Calling ISP, but most of time they pinpoint customer side or other side user(destination). I discovered this tool few years ago, and I used this tool, iBGPlay, for global BGP route path reviewing.
