[isp-bgp] Re: Suggested solution to prevent my prefixes from being suppressed

[mmostafa@...]

Dear James and colleagues , 
First of all im very gratefull for your contribution all of you , and
im really very happy to be a member of this BGP working group . 
Well , we have exactly 2 GTWs each one has a separte BGP session one with
FLAG NY ,and FLAG LNDN as i mentioned before we use flag NY as the main link 
while LNDN is a bckup for both up & downstream traffic except some small 
volumes of certain classes 
form my observation during the past 2 monthes i can say that our session 
with FLAG LNDN is more stable than FLAG NY , and attacks are of that type 
consuming B.W so what happen is we got BGP-SESSION down due to Hold timer  
expired + Some EIGRP sessions also reset due to hold time along DPVCs 
carrying the attack . 
Our traffic policy is implemented by sending our prefixes with two differnt 
communities and flag apply differnt LP for each path NY & LNDN
We confirmed with flag that our prefixes are of same attributes at thier 
edge routers so damping may be due to reannouncement 
I wana to confirm that Flag doesnt aply damping to its customers plus 
fastfallover is disabled from both sides as per our request . 
Regarding my suggestion which is advertiseing more specific and aggregating
at flag Edge routers keeping the as path information as its in as-set form : 
If im not the owner of the prefixs , i dont have  the right to aggregate 
these prefixes "" is this true or false ??
