Hello,
We are having routing problems with ANS. They are not
accepting our routes from AS3561. They were excepting
them just fine about a week ago, but around last week
end our routes dissappeared from their AS.
Current status, with AT&T as an example of a working routing status:
route-views.oregon-ix.net>sh ip b r ^1673_.+_6667
route-views.oregon-ix.net>sh ip b r ^7018_.+_6667
BGP table version is 4987768, local router ID is 198.32.162.100
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal
Origin codes: i - IGP, e - EGP, ? - incomplete
Network Next Hop Metric LocPrf Weight Path
* 195.74.0.0/19 12.127.0.249 0 7018 3561 5556 6667 i
* 195.197.0.0/16 12.127.0.249 0 7018 3561 5556 6667 i
* 195.218.64.0/19 12.127.0.249 0 7018 3561 5556 6667 i
* 195.238.192.0/19 12.127.0.249 0 7018 3561 5556 6667 i
Since all their NS and MX records are within their own network,
contacting them is rather impossible, so I turn to the NANO group
for helpful hints on how to resolve the problem.
Greetings:
Not sure when u saw a routing problem with ANS, but we hear the following
