[c-nsp] loss of advertised bgp route

[a. rahman isnaini r. sutan]

Few minutes down for any reason it might caused, BGP keepalive will no 
longer exchanged and peer assumed unreachable.
BGP connection closed.
During troubleshooting (layer 1/2), if this only few minutes, what if 
keepalive interval time extended ?

: Bill,
: I would have to say if they are dampening you and you are experiencing

: Did anything change since the older router such as how the circuit was

: Also you can route to a loopback interface to ensure it stays in the

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.

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?
