Bridging a VLAN together

I’ve got a router that is doing pretty basic routing, ether 1 is the WAN port and ether 2 is the LAN port. No nat. I’ve also got the need to pass another dhcp server through this router as we have a 2nd ISP that uses our hardware, but I need that ISP traffic to use the router like a switch. So I created a vlan ID2 on both ether1 and ether2, bridged them together, and it works just the way I need it to. Their entire network runs on vlan2.

The problem is now I’m trying to create a 2nd LAN bridge so I can use ether2 with a different vlan so I can issue the same IP addresses on ether2 and another remote router on vlan3. The problem is both bridges cannot exist at the same time or vlan2 quits passing traffic.

Should this work or is there another way to go about this?
