No, but at that point you are building a router anyway, so you might as well run the router software on the host directly instead of on the SBC host inside the main host. Keep in mind that most routers are just computers too. Sometimes they are low-power computers with special hardware components to offload specific tasks so you can trade power for specialisation (which also comes with a rigidity trade-off, you can't change the hardware after the fact like for new protocols).
