Re: Anycast and windows servers

Given your initial question was, I think, about the OSPF implementation
on windows - I used it on NT 4.0, when it was part of the routing and
remote access option, to implement fault tolerant routing through some
windows based firewalls.
It worked fine then. So long as you minimize the services running on the
windows box, it was stable enough.
Have not used window servers since NT 4.0, but I don't imagine its
gotten worse.

has their own clustering solution which will
perform failover. Sometimes choosing full vendor

With Windows 2003 Server they even support
geographically disperses failover. Info at:

Honestly, I do not know about OSPF (or BGP) on Windows,
however, you
can just static route to the Windows box(es). Sure, if
the OS hangs,
the interface will stay up and the static route will
still push bits at
the dead box, but it will work (FSVO "work").
Besides, how often does Windows crash? <snicker>
Hence the reason why I want the route to cease being
advertised if the box
"fails."
Connect the server(s) to APC MasterSwitch or equivalent
hardware. Monitor
the server box(es) for responsiveness. If/when it fails, the
monitoring
station can instruct the MasterSwitch to reboot (power cycle,
really) the
box. Stuff is pretty inexpensive (certainly less so than load
balancers).
I'm trying to avoid putting yet another server load balancer
box in front
of the windows box to withdraw the route so a different
"working" box will
be closest. It may be an oxymoron, but I'm trying to make
the windows
service (if not a particular windows box) as "reliable" as possible
without introducing more boxes than necessary.
My initial thought last night was in fact the use of load
balancers. But
then you need to think about redundant load balancers and so on.
