Hi all,

Anybody can give any suggestions for the situation below ?

My network is currently connected to two 2 ISPs and running a bgp those
links.
The first isp has 2 international link, but they don't have a direct link to
US. Recently, we just added a new link which is connected to the second isp,
this isp has a direct link US.

The bandwidth the first isp is 2 MB and 1 MB for the second link.

After adding the second link, most of the incoming traffic are going via the
2 second isp. This situation make the bandwidth utilisation on those two
link are not equal, the smaller bandwidth link is over utilised than the
bigger one.

So if there are way to solve this problem beside doing a manual selection by
as-prepend to a certain AS number?

Thanks and regards

Budi
