_100$ OR ^100$
How about Null AS Path “()” You can use AS Path regular expressions to create a null AS Path that matches routes that have originated in your AS.

Hi,
If I have R1 in AS 50 peering with R2 in AS 100. if I want R1 to learn routes only originated in AS100 only from R2, which as-path acl will be correct?
ip as-path access-list 1 match _100$
OR
ip as-path access-list 1 match ^100$
route-map FIL permit 10 match as-path 1
on R1 I apply this route-map incoming to R2
Regards,
Mohammad Zahed Saeed
