Greetings Jason-

Specifically, I have:

eth0: x.x.x.x/24
eth0.2: y.y.y.y/29
eth0.3: z.z.z.z/24

After bridging eth0 and eth0.3, devices on eth0.3 will utilize the same address space as that present on eth0 native (x.x.x.x/24). Of course, traffic to/from eth0.2 would continue to be functional. Traffic *does* need to operate in both directions, and yes there will be broadcast traffic originating from eth0.3, as a DHCP request, which would be answered by a DHCP server on the eth0 native connected network.

Thanks!
