Hi, I have multiple VLANs on an L3 switch with their own Virtual Ethernet interfaces (Cisco SVIs). I want to serve different DHCP addresses based on VLAN, but I don’t want to trunk all my VLANs to the OpenWRT router that runs odhcpd.
Instead, I can use ip helper-address on the switch to convert DHCP broadcasts (which would be stuck in their own VLAN) to unicasts sent directly to the router, and keeps track of the requesting subnet in the giaddr field . Does odhcpd support this, and if so, how can I configure it? I’m just using DHCPv4.
Thanks
