Just one question. If you terminate the wan fibre on a switch and put a redundant router behind it, the switch himself turns out to be a single point of failure, right? Or do you have a second uplink which terminates on a second switch which is also connected to the same carp router? Joerg.

Or do you have a second uplink which terminates on a second switch which is also connected to the same carp router? exactly that is what I usually do, spread uplinks over the two switches, interconnect the two switches, and connect one router to each switch. To what extent carp is beeing used depends on a number of factors, if I can I prefer two distinct bgp sessions. Which still means running carp on the inside / customer facing. -- Henning Brauer, [EMAIL PROTECTED], [EMAIL PROTECTED] BS Web Services, http://bsws.de Full-Service ISP - Secure Hosting, Mail and DNS Services Dedicated Servers, Rootservers, Application Hosting - Hamburg Amsterdam
