%BGP-6-ASPATH: Invalid AS path xxx 3300 (64603) 2008 received from
x.x.x.x: Confederation AS-path found in the middle

provider x'd out to protect the innocent, but saw this from ALL ebgp
peers.

Thankfully our main vendor included a knob to emulate cisco's
brokenness, so we magically stayed up.

Subject: BGP noise tonight?




Say, our alarms went off tonight when we saw a roughly tenfold spike
in 
BGP prefix announcement and withdrawal rates at RIPE's rrc00 and
rrc03
collection points in Amsterdam.  The trouble started around 20:00
GMT,
hit its peak by about 21:00 GMT, and has trailed off slowly since
then.

Looking at the worst-behaved prefixes and AS paths led me to put in  
a call to the tech support center of an unnamed Major Provider, who 
confirmed that there had been a major BGP event but would provide 
no specifics.  

So, what's going on out there in the NOCs tonight?  Inquiring minds  
want to know. --jim
