Routing

Hi all,

we have several links to our ISPs that are physically on 10G interfaces but have various commits on them. I'm trying to assign bandwidth to them so we can use unequal cost balancing to use links according to their commit rates.

I'm trying to use communities that look like this:

community BW-1.5G members bandwidth:XXXXX:1500000000;
community BW-2G members bandwidth:XXXXX:2000000000;

(XXXXX is our ASN)

and the assign them to a term in an import policy for a specific peer.

The problem is that I'm not seeing traffic distribution according to the link commits but I see that the traffic is being equally distributed across all links. 

Perhaps I'm doing something wrong with the statements as there is conflicting info in the documentation  as some say use bytes and other say bits?

Thanks in advance for any help.

Hi,
Just out of curiosity- was you following this article?

It was one of the articles I was using to configure this. I was following these articles:
