I've setup 0/2 for management with 10.0.0.2. Bundle 1 has 10.0.0.3. DHCP server has 10.0.0.1.
I can ping 10.0.0.1 from uBR. I can ping 10.0.0.2 and 10.0.0.3 from DHCP server. DHCP server gets request from 10.0.0.3 with giaddr of 10.0.0.3 and sends a response, but the modem say it never recieved a response.

What are you using as a DHCP server? What is your config? What are you seeing in the DHCP server logs?
I have tried several different DHCP servers. Currently using TFTP32's dhcp server. 7246 shows set giaddr address set to 10.0.0.3. DHCP server says recieved discovery from 0.0.0.0 (MAC of modem) with giaddr of 10.0.0.3 and offering 10.0.0.4. Modem log shows no DHCP response received.
Thanks,
Leo
Use giaddr without strict and use ip routing - it's UBR however :)
I think you should have a different network for the modems and the ethernet/dhcp
example:
dhcp 10.0.0.1/255.255.0.0
cmts ethernet 10.0.0.2/255.255.0.0
bundle 10.1.0.1/255.255.0.0
in the dhcp put a route
ip route 10.1.0.0/255.255.0.0 gw 10.0.0.2
dhcp should have a pool for modems 10.1.0.2 to 10.1.255.254
Got it working... my only problem now is that when CPE's renew there IP address I loose the HFC MAC address that was originally populated using the ip dhcp relay option command. Is there a way to force unicast renewals to be relayed?
Thanks,
Leo
1.enable ip dhcp relay information
2. bundle ip address secondary for cpe
Already did that... I get the HFC mac on initial CPE lease, but not on renewals.
