Re: Q on what IGP routing protocol to use for supplying only gateway address

At least a few years ago, Windows OSPF was a port of Bay RS, which was
really Wellfleet code. So far, whenever I've needed to look at Windows and
figure out how it did something, knowing RS usually gave me the answer.

If this was 5+ years ago, I'd have said RIP as it works great for supplying
only gateway address, but I want RIP to go RIP and will

Any suggestion as to what IGP protocol is best for this scenario?
by the routing daemons on most *NIXes out of the box. I don't know about
not use it again. So yes OSPF seems like best choice, but I was
hoping something simple for gateway-only is available. I've no idea
yet how to deal with Windows (all win2000 and win2003), anybody?
VRRP for the non-Cisco. I've recently had to deal with some situations, in
VoIP, where the critical Call Agents have to stay in communication even if
physically distant. 802.1w seves nicely to share a subnet between two
geographically separate sites. Admittedly, one can reasonably count on dual
OC-192s, diversely routed, and each connected to two switches at either end.
Are you doing anycasting or something?
Yes, anycasting will be involved but only for very small number of
servers (all linux) - that is kind-of separate issue. The equipment
itself however will only see local gateway addresses (obviously), so
it should not care or know about it.
If simple redundancy in the default gateway is the goal, another (and
probably simpler) method is to implement HSRP or GLBP between your routers
which are serving the hosts in question.
Can't use HSRP in this case (or IVRP or whatever else its called with
non-cisco options) - too long to explain why.
