I'm a server guy but have taken over our networking as we are downsizing and trying to come up to speed as quickly as possible. I have a 6509 switch that routes traffic to the internet thru one provider. But have added a point to point t1(and added cisco 2511) to a customer . How do I configure the 6509 to route only certain http traffic(that is going to customer)thru the 2811 and over the point to point t1. So basically all internet traffic will go through the 6509 to the one provider but anything going to a ceertain url will now go to 2511 and over point to point t1.

Thank you

Two routes on 6509 should be good enough for this unless you need more granularity.

ip route <2511 router>

ip route

First route will make sure that you will direct all traffic going to specific IP toward 2511.

Second route will send the remaining Internet traffic towards ISP connected to 6509.

Please note that using first route not only HTTP but all other traffic going towards that specific IP will be send towards 2511. If you want to be more specific and want to match just HTTP traffic on that specific IP, you will need to use Policy based routing.

Yes, if you need to route only certain http traffic(that is going to customer subnet X)thru the 2811 then you'll need Policy Routing (PBR) so that the traffic matching an ACL (permit all tcp port 80 traffic destined for subnet X) is sent to the next-hop address of the 2811 interface
