So i understand that unknown CPEs and Cable modems will request an address from the primary bundle cable helper address using the primary ip address as the giaddr. (Default behavior)
So now some CPEs should a sub-bundle if they get a IP in the subnet under that sub-bundle. What happens when this CPE renews the IP again, will it use the helper address under the sub-bundle or use primary bundle? Can these helper address's be different? Assuming all the routing works and they point to the same DHCP server?
I want to create a VRF under the sub-bundle, but i don't want to leak routes between the main bundle (Global Routing) and the sub-bundle (VRF). So i would have a secondary NIC on my DHCP server that just handles dhcp renews from the sub-bundle.
