This is a case of Load Sharing vs. Load Balancing; very important difference!
And unfortunately , this is out of your control ... based totally on BGP hop counts. On a related note - I would like to drop a question to the group: Similar situation; i.e. - we have dual frac-DS3's to two ISP's and we are using BGP for basic redundancy/load sharing. The question now is how would we do bandwidth management in this situation? has signed us up for providing guaranteed bandwidth, thank-you-very-much>>. Specifically - say we have 6 clients, and want to enforce bandwidth cap's on their usage . The best we have come up with is 1 add another layer of routers between our Pices and our border routers ... use HSRP groups to traffic shape specific clients to specific "middle" routers by default. These new "middle routers" would perform the rate-limiting and then forward to the border routers. The border routers would receive only partial routes and iBGP would route those accordingly, otherwise default to send to default gateway. 2 get some third party - Packeteer and use this for the rate limiting / flow control. Still use iBGP + HSRP groups for "ISP client" routing and initial traffic shaping . Any thoughts? Have we overlooked something; the "automagic command" that makes this work cleaner? Some other product that is all-encompassing and functions as a magic bullet for this ... Thanks!

[7:40242] I'm assuming your getting full routes from each provider. You will most likely get a rough load balance based on the randomness of the sites your users are connecting to and your upstreams a roughly equal, i.e. 90% of your routes are not learned via provider A. But your not going to get a 50/50 per packet load balance between 2 differant poviders nor would you want to.
