I had sent an email on the sanog mailing list. Here is the email:

Subject: RR advertising only one route ..
To: sanog@...

Hi,

My RR announces one BGP route out of the two that it has. Because of
this the clients only see one route and use only that path. Because of
this the link utilization has gone in O(90%) while the other remains
under utilized (less than 20%).

I need to make the clients use both the links, for which the RR would
need to send me the two routes for that destination. Can something be
done about this?

One way is to break the advertisements into blocks of /19 and /20, but
this is all manually driven. Any brighter ideas?

I remember there was this discussion long time back about extending
BGP to advertise multiple paths. Any headway there?

Abhishek
