Regarding the negatives to BGP: 1. uneven load sharing -- If you have 2 circuits with the same ISP, this is not an issue. Otherwise, if you have a circuit with 2 ISPs (as the original poster indicated) -- load sharing becomes uneven, and requires a more complex configuration. And constant tweaking... How does Rainfinity load-balance incoming traffic? 2. complex configuration -- Depends. If you don't care that your load is balanced, you configuration can be quite simple. Especially if both circuits come into the same router. If the circuits come into different routers, then the configuration gets a little more complex. 3. requires AS number and cooperation from both ISPs -- Requires little effort, and a little $. The only cooperation you need from the ISPs is for them to configure a BGP session with you, which any ISP should be able to do in their sleep. I would not classify this as a negative to a BGP solution. 4. giant routing tables that eat gobs of router CPU and RAM, etc -- ;) A full routing table is in the neighborhood of 88000 network entries. I have recommended, that if you are going to take full feeds from 2 providers on one router that the customer have 128 megs on at least a 36XX Cisco. What is the list price of a Rainfinity solution? What are the maintenance contract costs? -iden_fw From: "Mark L. Decker" <[email protected]>
