radius source-interface (BNG)
To force RADIUS to use the IP address of a specified interface or subinterface for all outgoing RADIUS
packets, use the radius source-interface command. To prevent only the specified interface from being the
default and not from being used for all outgoing RADIUS packets, use the no form of this command.

Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task
IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator
for assistance.
Use the radius source-interface command to set the IP address of the specified interface or subinterface for
all outgoing RADIUS packets. This address is used as long as the interface or subinterface is in the up state.
In this way, the RADIUS server can use one IP address entry for every network access client instead of
maintaining a list of IP addresses.
The specified interface or subinterface must have an IP address associated with it. If the specified interface
or subinterface does not have an IP address or is in the down state, then RADIUS reverts to the default. To
avoid this, add an IP address to the interface or subinterface or bring the interface to the up state.
The radius source-interface command is especially useful in cases in which the router has many interfaces
or subinterfaces and you want to ensure that all RADIUS packets from a particular router have the same IP
address.
