Well we, Genuity, use to use Cisco Distributed Director to do this. Basically it was a DNS server that ran on a Cisco Router, and could use a lot of different metrics to give an answer, which included routing based metrics. Johno

Both have a DNS MX record metric of 10 so a bastardized round-robin takes place. This does not work so well when one site goes down. My solution will be to place a load balancer in a hosting site (virtual, of course) and have it provide HA. But what about HA for the LB? At first glance anycasting would seem to be a great idea but there is a problem of broken sessions when routes change. Have any of you seen something like this work in the wild? -- Joe Hamelin, W7COM, Tulalip, WA, 360-474-7474
