[isp-bgp] Problem with RRs

["Tulip Rasputin" <tulip_rasputin@...>]

Hi,

I have a Route Reflector (RR) in my topology. It receives two equal cost BGP
routes (from clients R1 and R2) but it announces just one to its downstream
peer R3. The RR is selecting R2 based on the lower Router ID. So, it just
announces the route it learns from R2. R3 thus ends up sending all its
traffic to R2. For R3, R1 is closer than R2. Is there a way i can have R3
sending all the traffic to R1. Also note that in my network, R3 can
independently reach both R1 and R2 and it need not go through RR for this.

 R1         R2
   |__RR__|
         |
       R3

I did talk to some folks and they said that i should set the "nexthop self"
on the RR, so that all the traffic flows via the RR, which can split the
load between R2 and R3.

Is this the only solution? Or is it mandated that the RR come in the
forwarding path?

Thanks,
Rasputin
