Hello Marko ! Sorry for not giving the feedback for the issue we had a couple of weeks ago.
The problem was BGP conflict. Our isp was announcing the IP range with his AS number and another ISP in US was still advertising the same IP range with another AS number to the Internet. So, when troubleshooting through reverse traceroutes, the traffic was sent to US when the AS path was short and to our country when our AS path was shorter than he one originated from the US. We finally arranged that with the provider in US and everything was fine. But actually, we sometimes have access to some web sites but can't open or download something at sometimes and everything get's back to normal without any configuration change. I can't understand what is going wrong. Thanks Luc Valere BIKANDA ________________________________ From: Marko Milivojevic <[email protected]> To: VALERE BIKANDA <[email protected]> Cc: ccie_rs <[email protected]> Sent: Mon, May 10, 2010 6:38:05 PM Subject: Re: [OSL | CCIE_RS] Application Layer Troubleshooting I'm sorry to be rude, but didn't we go through all this with you couple of months ago? -- Marko Milivojevic - CCIE #18427 Senior Technical Instructor - IPexpert YES!
