[c-nsp] loss of advertised bgp route

[OCOSA ListAcct]

Bill,
I would have to say if they are dampening you and you are experiencing 
connectivity problems find out what is going on...(i.e. cable, module, 
interface, PA, duplex problem maybe I doubt it)
Did anything change since the older router such as how the circuit was 
provisioned to you? It could be the interface on your router though. 
Also you can route to a loopback interface to ensure it stays in the 
table....

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.

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?
