Hi,
I can really relate to that problem, I faced it about a year and a half
ago while a client of mine wanted to divide the traffic in to categories,
European traffic and U.S traffic and all the reset doesn't really matter to
him.
The way I though of was involved in a lot of dirty work, I used the ARIN
database to find all the European and the U.S AS's, after I had the two
lists I started building appropriate regular expressions to all of the
statements.
After having finishing writing all the regular expressions you need to
attach them to a route-map which will specify the properties of the regular
expressions, by using the local-preference attribute for setting it's a path
and for it transitive property in the IBGP peering.
In the end after finishing all those tasks and you want to try and fixing
the returning traffic, set another route-map that it's purpose is to prepend
additional AS's to your networks advertisement.
O.K good lack and I hope I have helped you.

Subject: a real bgp question
Dear group,
I come across a real bgp question in my work,that is:
I want to load balance and backup between my 2 ISPs,they also have their own
AS numbers and have a direct connection between them as well,I use 2 edge
router running iBGP with eachother and eBGP with my 2 ISPs.The question is :
.if I want to make the traffic for ISP1's AS pass through one connection and
the other traffic for Internet through ISP2,how to config my edge router in
my one AS?
.if I have 2 ASs,what about the story?
Avobe 2 conditions,does it need some config in my ISPs BGP neighboors?
I am appreciated if you can give me some idea.
TIA
Dean
