I was reading over the howto at the above link, and I got hung up on step 6. Are they talking about a default gateway/gateway of last resort here? They use the term "default router", so I didn't want to assume that they meant default gateway. Just an FYI, I am learning about inter-VLAN routing on layer 3 capable switches, and I've actually got it working using up to step 5 in the above howto in a lab environment, but when I take away the default gateway address on my host machines, they can't see each other any longer. I pretty much deduced that this is because I haven't set up a default gateway on the switch itself, which leads back to why I'm asking you this question in the first place... Is Step 6 exactly what I need to do, and if so, if I'm using a routerless setup (just layer 3 routing on the switch (a 3550)) what IP should be used as this address?
Attached is a pretty diagram of what I have so far. Again, the hosts can ping each other when they have a default gateway programmed into them (just like the diagram says), but as soon as I remove that default gateway, they get all screwy.
