route-map & BGP question

in CCNP
I accepted this circuit yesterday and I configured a bgp peering with the ISP. At the same time, I wanted to check the circuit for any drops for the next 24 hrous so I setup a route-map which would keep the old circuit as the best path for BGP.
I want to know how to remove the prepend path from BGP and make this the best path.
Bassically this is what I configured:
route-map AS-PREPEND permit 20
set as-path prepend 65900 65900 65900
!
Router bgp 65900
Neighbor 10.70.252.49 remote-as 65000
Neighbor 10.70.252.49 route-map AS-PREPEND out
!
Thank you for all your help in advance!

That will equal the links, you need to remove it here and apply it to the other circuit if you do not wish to prefer the old circuit (with your addition to influence outbound traffic from above).
Define quickly?
Cisco Learning Lab has a lab just on this topic.
As the others said, prepending AS is to influence the peers to use the circuit you want them to use, rather than dictating which circuit you'll use. And that really only works if the two circuits are on different AS. Basically you're artificially telling the peers one path is longer to you than the other. It's about the only attribute you can push onto others.
For influencing your outbound choice:
You can increase the weight on the preferred neighbor if you are using a Cisco router.
You can also set local-preference, which is a non-proprietary attribute.
Do a soft reset on the inbound to speed up the change, otherwise it could be several minutes for you to see the effects.
What will happen after several minutes for him to see the effects? He needs to perform either a hard or soft rest for the policy to take affect!
