we config the bgp to influence inbound traffic. the config is following.
We would like 202.x.7 come in PA (provider A) and 202.x.10 come PB (provider B). In US site, we have one Internet circuit. we find that four ip address always goes to "provider B" even we add ten AS number append to it. any idea to influence the inbound traffic to go different circuits in HK? pls advice
Can you check the routes on one of the public BGP servers on the Internet to see whether the prepended AS Path still exists for that particular route. It's possible providerA might be summarizing the routes and advertising it out to the Internet whereas providerB might be advertising that network as it is and that would cause providerB to be the preferred path for that network despite the prepended AS path. Talk to providerA about this and they should probably be able to help you with this.
If you are still having issues can you provide more info about the problem for us to find the issue.
Did you look up on any public BGP server the route to your network. It could be how providerA advertising your network out to the Internet may be the problem. As I stated before you would definitely want to talk to providerA as their involvement may become necessary here. It appears you don't want to reveal your public address and that makes us unable to do the route lookup ourselves.
