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.
The problem is completely intermittent. 99% of the time everything =
works fine. 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)
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.
So, my point and questions:
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.
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 ?
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.
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.
Thanks
Eric
