i dearly do wish that something like a "service advertisement protocol" existed, that did what OSPF ECMP did, without a router operator effectively giving every customer the ability to inject other customer routes, or default routes.
This stuff about customers and things sounds too hard. Steve, have you actually had to do anycast without having control of the routing hop in front of your service providing hosts, or is this getting unnecessarily complicated? I'd imagine that the ability to install routing equipment would be a pre-requisite for any anycast service deployment.. Perhaps what would make more sense here is Foundry (F5, etc.) building an anycast feature - anycast prefixes are withdrawn when a cluster relying on that anycast prefix goes below a threshold. These load balancing switches already do all this service health check stuff and have done for years, so why are we re-inventing the wheel? -- Nathan Ward ps. I'm amused that your message that started with "i think the minutia is good, especially after a long weekend of layer 9 threads." ended with a paragraph of L9 :-)
