Dear admin,

I got helped from Huawei HEDEX about configuration of  BGP AS Regular Expression for NE40E.The solution I got are given below:

Actually it helped me much to enhance my technical skill .. Thanks to Huawei.

A： 
You can use regular expressions in the ip as-path access-list command with Border Gateway Protocol (BGP) 
The following are a few examples: 
ip as-path access-list 2 permit _7532$   
:allow the networks that have originated in AS 7532 
ip as-path access-list 11 permit _6451[2-9]_   
:allow the networks that have passed through AS64512,AS64513.....AS64519 
The rules of the regular expression and more examples can refer to attachment,.  

Thanks great success story .............
