Hello, I have two CCR doing BGP, one with Cogent and the other with Level3.

The incoming traffic is arriving Ok by the best BGP route, but I don't know how exactly configure the gateway to to out traffic.

Now I have assigned:

CCR-Cogent: 10.0.0.1
CCR-Level3: 10.0.0.2
CRS: 10.0.0.3

I need to change the gateway of the hosts to select wich provider (cogent or level3) use for the traffic out.

There are some documenation about how to configure the traffic out to use the best route?

Thanks!!

Hi,

you could configure the CRS to do policy based routing. This way you have the control about what host uses which provider for outgoing traffic.
But depending on the desired / required bandwidth the CRS might not be able to handle the traffic load when doing L3 forwarding.
