Hi All,
  We've installed a new 7609 recently (up 3 weeks) and run BGP to connect to 
our upstream provider. We are announcing two prefixes, a /16 and /24. Since the 
install I've noticed connectivity to the ISP has gone down for a few minutes 
about 10 times, never during business hours. A couple of days ago this happened 
during business hours and we found out that our /16 was being dampend by the 
ISP due to our router not consistently advertising the prefix. 
   
  In BGP config we have both routes in with network statements and a neighbor 
prefix-list out with both prefixes. Also in ip routes we have "ip route x.x.0.0 
255.255.0.0 Null0" which should keep the prefix advertised at all times as 
well. I'am running IOS 12.2(33)SRA3 and Cisco cant find any issues at the 
moment...can anyone shed some light on this? 
   
  Thx, Bill
