Basically we suscribe to 2 ISP, so i believe they have different AS.
We also have our own ASN number , example 12345

We asked both isp to aggregate our ASN number .

Question, seeing that both ISP aggregate our ASN number, we are also confuse which path will it get?

Can we achieve a load balance of the incoming traffic here?

Right, you send your /24 to each ISP, but do they advertise it to their AS peers or do they aggregate into a larger address block which they advertise to their BGP peers?  Do they advertise it at all to their AS peers?

With BGP, the question is, once they pass your /24 to your ISPs, what do they do with it?  If you have your own AS, they should pass your /24 along, but do they?

yup they pass our /24 along our ASN . both ISP did the same
