Basically I was thinking on these lines.
If i have an AS path {1 2} [3 4] { 5 } then is it possible to pull the AS in the last segment and merge it with the first segment? This would give me {1 2 5} [3 4]. This way i dont need to
Since i smell some traces of sarcasm here.

Hi,
Is the order of AS numbers (except for perhaps the first one which
denotes the AS the route was originated from) in the AS_PATH in BGP
important? In fact, does anybody even care for the first AS number
that appears in the Path?
AFAIK, AS numbers in the BGP serves two purposes. It helps in lo
Hi,
I was looking at route-views.routeviews.org for the BGP routes and i
dont see any AS-Sets whatsoever. Are BGP routes with AS-SETs not
generally leaked into the wild?
Is this the case?
I am under the impression that AS_SETs are generated whenever there
are some routes that are aggregated. Is
coz i assumed that everyone wants to block such sites.
sorry if i hurt some feelings.
apologies,

Again, I am not discussing "censoring ideas". I want to know if its

No, that wasnt my point. I just wanted to make sure that my
understanding of banning a hostname was indeed correct. We can this
way atleast block all
Hi,
I have a doubt which i am sure a lot of people in this list would be
able to help me with.
There was news that terror groups like Al Qaida, etc. are using
internet to promote their terror links and these web sites provide
online training on how one could assemble bombs, etc.

Hi,
There are ways to add static routes that can be blackholed. I can
understand the utility of such routes if those are installed in my
forwarding table. What bewilders me is why would anyone want to
advertise "blackhole" routes using say, BGP?
Is it only to prevent some sort of DoS attacks or
