I suggest showing them the results of
"sho ip bgp damp damp | incl 7018"
from route-views.oregon-ix.net (or even from route-server.ip.att.net). I get close to 800 prefixes as being suppressed (some for up to an hour). More details can be seen via:
"sho ip bgp damp flap reg 7018"

Has anyone else noticed any ususal oddities in AS7018 over the last half hour or so? I saw BGP advertisements flap en masse and we are still experiencing strange connectivity issues that reek of inconsistent CEF tables.. Their NOC claims there are no problems.
