Thank you all for your responses so far. I've spent a few days digging through the manual looking at commands and when that failed, turned here. So far everything that has been suggested is either (I think) more than what I'm looking for at the moment (gateway of last resort, DHCP servers, etc) or something I've already done/tried. The trunking is all set up just like you all have specified, as has the port setup and routing setup (minus, in one case, the ip helper address for a DHCP server). To simplify the problem, I dropped it down to one switch so now one host comes in on ge.1.1 on VLAN2, and the other host comes in on ge.1.2 on VLAN3 on the same C3 switch. Nothing else is connected. The subnets are still the same: VLAN2: 10.10.20.1/24 VLAN3: 10.10.30.1/24 Host 1: 10.10.20.100 Host 2: 10.10.30.100
All interfaces are administratively up, and VLANs 2 and 3 are operationally up. Both ge.1.1 and ge.1.2 have VLANs 1 and 2 untagged in the egress list (and I've tried it with only that ports VLAN in the list). The MAC and ARP tables still see both hosts, and it still refuses to route traffic between subnets. Both computers can ping their respective gateways, but not the gateway of the other subnet. I really feel like I'm missing some small part that makes this all work.
