I am multihomed to two ISP's. I want to choose ISP#1 for reaching the IP 
addresses which belongs to ISP #1 and its directly connected ASs and use ISP 
#2 to reach all other IP addresses. I have a default running towards ISP#2 
and learning specifics from ISP#1. I tried filtering routes I recieved from 
ISP #1 using as-path acl as below:

IP AS-PATH ACCESS-LIST 20 PERMIT ^2914_[0-9]*$
