Re: Q on what IGP routing protocol to use for supplying only gateway address
From: "william(at)elan.net" <firstname.lastname@example.org>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.
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.
