There's a fourth. I used to manufacture something called the Web Gateway Interceptor which was topologically a router. It wasn't competitive as a router, either in price, performance, or number/kind of interfaces. But you could put it in parallel with another router and integrate it into your OSPF mesh and use OSPF link costs to make it be the primary path only while it was up. HSRP would have worked the same way, and I'll admit that it's a lot simpler to do (though I'm not sure it's an open standard yet?) -- Paul Vixie <[email protected]>
