And using the tools I'm most familiar with. So yes, I've considered a routing approach, but it feels overly complex and is likely to have a higher convergence/failover time (at least without major tuning). I'm perfectly happy having a potential SPOF without an automatic failover for the replication link, but if there's a trivial way to achieve it I'll go for it. ^_- Christian -- Christian Balzer Network/Systems Engineer chibi at gol.com Global OnLine Japan/Fusion Communications http://www.gol.com/
