DHCP Radius Proxy
DHCP Radius Proxy mode assumes that the Operator has deployed RADIUS servers within its billing solution.
DHCP Radius Proxy mode can be enabled by setting the bras_dhcp_mode
parameter value to 2 in the fastdpi.conf:
bras_dhcp_mode=2
More detailed information regarding the DHCP Radius Proxy can be found in the appropriate section.
Description of the VSA attributes for the DHCP options relevant for the DHCP Radius Proxy mode can be found in the manual.

The DHCP Relay Agent mode is enabled by setting the bras_dhcp_mode
parameter value to 1 in the fastdpi.conf file:
