<DIV><FONT face=Arial size=2>I apologize if this is off-topic - I rarely
post, mostly just monitor. I am not posting this to [nsp] or [isp-bgp] for
I don't believe the following is a configuration problem on my side, but an
operational one of a certain provider. I am not going to sling dirt or put
actual names / ASN, etc for now. I want to list the problem and if it is
relevent I can post more specific data or be contacted offlist with suggestions
or from the provider.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The problem is completely intermittent. 99%
of the time everything works fine.</FONT><FONT face=Arial><FONT size=2> I have
begged the customer to get their ASP's ISP involved since I believe that is
where the problem lies. They claim it is my problem since we connect to
them.....(Don't want to start a war here...I know)</DIV></FONT></FONT>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I am Provider A and my customer cannot connect
to an ASP through Provider X. The problem lasts for what seems to be exactly 10,
15 or 30 minute intervals. I am announcing my /19 broken up into multiple
/22 and /21's. It is only 1 of the /22 that has the problem. One of
my links is not going down and I do back backup routes through multiple
providers. It took me almost a month to confirm the problem because they
would call be *after* it happened and everything would look fine. I put
some monitors on the destination site and it will never test bad since the
monitors were on other subnets. They finally called me while it was
occuring and I did confirm I could not reach the site from any of the IP's in
that certain /22 subnet.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>So, my point and questions:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Has anyone ever heard of such a problem
? I tried to search some archives and google - but I can't really figure
out what to search on that won't result in 1000 + matches.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Is there any function or problem that might exist
for exactly 10, 15 or 30 minutes (i.e. BGP Flap, subnet block filter / ACL ?)
over and over ?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Should I contact provider X dircectly ? Will
they work directly with me ? I believe my customers ASP opened a ticket
with their ISP but with all the layers and short time frame of the issue I don't
think it will get resolved quickly or easily.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Responses online or offline welcome. If
anyone wants more specific info posted to the forum (IP subnet blocks, Provider
X, ASN, etc) please let me know.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks</FONT></DIV>
