That's not too unusual. They've got to sell cheap to keep up with the competition. My current favorite switch (note: switch, not switch/router) happens to be the Foundry FastIron, nice sexy switch, but a bit pricey. Seems to do vlans correctly, which is useful in the event that you're feeding over a gigabit fiber or something :-) > > If you have one router and one machine on a network, with OSPF you have > > exactly two ARP entries - and no need for the router to ARP for each virtual > > server.

But I know I'd prefer to have 200 actual servers not each advertising 50 additional addresses (~= 10,000 ARP entries possible). The 200 ARP entries plus 10,000 routing table entries would be manageable for the worst-case OSPF implementation. The 10,000 ARP entries would overflow lots of crappier switch equipment. -- ...
