Hi Michal,

The example shown are just a few of it. In actual, there are thousands of them and not possible to specify by the actual AS. We need to use something less specific.

What I want should be,
for example 2 AS, the AS path that match should be 500 "any AS# with/without prepend" for example 3 AS, the AS path that match should be 500 "any AS# with/without prepend" "any AS# with/without prepend"

Is this possible?

I hope I could state the requirement clearly.

Regards

Hello,

>For example:-

>2 AS away
>500 10
>500 10 10 10

My version:

^(500_)+(10_)+$

>3 AS away
>500 30 40
>500 500 30 30 40

^(500_)+(30_)+(40_)+$

Best Regards,
grzybek
