BGP Mutihoming (Load Balancing)
Posted on 2007-04-04
We are building a new datacenters and in each datacenters we have mutiple connections out to the outside world. we are planning to use private AS provided by our ISP, so we will have IBGP full mesh on our internal routers and peer up with our ISP Public AS. We will redistributes routes in to IGP (EIGRP) and then routing decisons towards the internet will be made by EIGRP. My question is, does it make any difference if we get a full routing information from the ISP or partial or just a default route. My personal decision is i dont think we need a full routes (120,000 routes) becaus this put more load on our IBGP routers and also redistributes in to EIGRP will also cause issues. (Too many routes to manage). Please advise.
and thanks in adavance guys......
