Subscriber-aware NAT

Subscriber-aware information must be supplied to both nodes (active and standby) through RADIUS accounting.

With NOKIA BNG, the following configuration ensures that subscriber information is sent through RADIUS to more than one target:

*A:BNG1>config>subscr-mgmt>sub-prof# info
----------------------------------------------
            radius-accounting
                policy "acct-nat-1" "acct-nat-2"
            exit

Accounting policies contain respective NAT node destinations and consequently the subscriber information is sent to both NAT nodes.
