Thank you all for the replies. I did some more reading and testing, and I've had a little success, but I still don't have VLANs working on the ESXi host.
@lleachii, I did some reading on the links provided, but like I said, there's not a whole lot in there about trunking on a device that doesn't have an internal switch.
@jeff, @mk24, I am not running OpenWrt in a VM. R2 is an Actiontec MI424WR Rev. D, which was provided by Frontier (back when they were called Verizon). It does not have an internal switch, so it seems I do have to configure VLANs using interface.vlan notation. I've configured everything in LUCI thus far, and here is what I have currently in my network configs:

The main part to look at here are the settings for interfaces vlan10 and vlan100 on R2. I have bridged the VLANs from eth0 (lan ports) to eth1 (wan port). Keep in mind R2 is functioning as a dumb AP and has LAN/WAN interfaces bridged already and firewall disabled. Interface eth1 on R2 is connected to R1. Using this configuration, I am able to pull a valid IP address for R2 from the DHCP server on R1 (within the IP range I configured for those VLANs), so VLANs 10 and 100 are working between R1 and R2. However, I am not able to connect from any virtual interface configured for VLAN 10 or VLAN 100 on an ESXi guest. I tried static assigning an IP address with no success. I'm not really sure how ESXi assigns VLANs to the outbound packets, but I can capture some traffic with wireshark if anyone thinks it will help diagnose the issue.
EDIT: The article here suggests that ESXi follows the 802.1Q standard.
I am also considering putting down twenty bucks for a cheap "smart" switch to see if I would be able to trunk the VLANs with that. I'm not ready to invest in a robust managed switch when all I really want are VLANs.
As always, any thoughts are appreciated.
