[Possible Spam]Re: dhcp with multiple dhcp-relay routers

	Just ran a quick debug again so I get my story straight

The key in dhcp_sqlippool is

       pool_key = "%{%{DHCP-Client-Identifier}:-%{DHCP-Client-Hardware-Address}}"


Debug is as follows

Tue Oct 28 16:32:24 2025 : Debug: (1121)   DHCP-Gateway-IP-Address = 10.180.144.2
Tue Oct 28 16:32:24 2025 : Debug: (1122)   DHCP-Gateway-IP-Address = 10.180.144.3
Tue Oct 28 16:32:24 2025 : Debug: DHCP: Existing IP: %{reply:DHCP-Your-IP-Address} (cid %{DHCP-Client-Identifier} chaddr %{DHCP-Client-Hardware-Address} giaddr %{DHCP-Gateway-IP-Address})
Tue Oct 28 16:32:24 2025 : Debug: attribute --> DHCP-Gateway-IP-Address

These are the same request being relayed from the two different routers.   One matches the existing ip the other does not as the query is using the giaddr.  Unless I am misunderstanding the debug.

  You can upgrade on a test machine.  And see if the queries have been updated.

  And.... what does the debug output say?
